+
+## Creating from Scratch
+
+**Read [pptxgenjs.md](pptxgenjs.md) for full details.**
+
+Use when no template or reference presentation is available.
+
+---
+
+## Design Ideas
+
+**Don't create boring slides.** Plain bullets on a white background won't impress anyone. Consider ideas from this list for each slide.
+
+### Before Starting
+
+- **Pick a bold, content-informed color palette**: The palette should feel designed for THIS topic. If swapping your colors into a completely different presentation would still "work," you haven't made specific enough choices.
+- **Dominance over equality**: One color should dominate (60-70% visual weight), with 1-2 supporting tones and one sharp accent. Never give all colors equal weight.
+- **Dark/light contrast**: Dark backgrounds for title + conclusion slides, light for content ("sandwich" structure). Or commit to dark throughout for a premium feel.
+- **Commit to a visual motif**: Pick ONE distinctive element and repeat it — rounded image frames, icons in colored circles, thick single-side borders. Carry it across every slide.
+
+### Color Palettes
+
+Choose colors that match your topic — don't default to generic blue. Use these palettes as inspiration:
+
+| Theme | Primary | Secondary | Accent |
+|-------|---------|-----------|--------|
+| **Midnight Executive** | `1E2761` (navy) | `CADCFC` (ice blue) | `FFFFFF` (white) |
+| **Forest & Moss** | `2C5F2D` (forest) | `97BC62` (moss) | `F5F5F5` (cream) |
+| **Coral Energy** | `F96167` (coral) | `F9E795` (gold) | `2F3C7E` (navy) |
+| **Warm Terracotta** | `B85042` (terracotta) | `E7E8D1` (sand) | `A7BEAE` (sage) |
+| **Ocean Gradient** | `065A82` (deep blue) | `1C7293` (teal) | `21295C` (midnight) |
+| **Charcoal Minimal** | `36454F` (charcoal) | `F2F2F2` (off-white) | `212121` (black) |
+| **Teal Trust** | `028090` (teal) | `00A896` (seafoam) | `02C39A` (mint) |
+| **Berry & Cream** | `6D2E46` (berry) | `A26769` (dusty rose) | `ECE2D0` (cream) |
+| **Sage Calm** | `84B59F` (sage) | `69A297` (eucalyptus) | `50808E` (slate) |
+| **Cherry Bold** | `990011` (cherry) | `FCF6F5` (off-white) | `2F3C7E` (navy) |
+
+### For Each Slide
+
+**Every slide needs a visual element** — image, chart, icon, or shape. Text-only slides are forgettable.
+
+**Layout options:**
+- Two-column (text left, illustration on right)
+- Icon + text rows (icon in colored circle, bold header, description below)
+- 2x2 or 2x3 grid (image on one side, grid of content blocks on other)
+- Half-bleed image (full left or right side) with content overlay
+
+**Data display:**
+- Large stat callouts (big numbers 60-72pt with small labels below)
+- Comparison columns (before/after, pros/cons, side-by-side options)
+- Timeline or process flow (numbered steps, arrows)
+
+**Visual polish:**
+- Icons in small colored circles next to section headers
+- Italic accent text for key stats or taglines
+
+### Typography
+
+**Choose an interesting font pairing** — don't default to Arial. Pick a header font with personality and pair it with a clean body font.
+
+| Header Font | Body Font |
+|-------------|-----------|
+| Georgia | Calibri |
+| Arial Black | Arial |
+| Calibri | Calibri Light |
+| Cambria | Calibri |
+| Trebuchet MS | Calibri |
+| Impact | Arial |
+| Palatino | Garamond |
+| Consolas | Calibri |
+
+| Element | Size |
+|---------|------|
+| Slide title | 36-44pt bold |
+| Section header | 20-24pt bold |
+| Body text | 14-16pt |
+| Captions | 10-12pt muted |
+
+### Spacing
+
+- 0.5" minimum margins
+- 0.3-0.5" between content blocks
+- Leave breathing room—don't fill every inch
+
+### Avoid (Common Mistakes)
+
+- **Don't repeat the same layout** — vary columns, cards, and callouts across slides
+- **Don't center body text** — left-align paragraphs and lists; center only titles
+- **Don't skimp on size contrast** — titles need 36pt+ to stand out from 14-16pt body
+- **Don't default to blue** — pick colors that reflect the specific topic
+- **Don't mix spacing randomly** — choose 0.3" or 0.5" gaps and use consistently
+- **Don't style one slide and leave the rest plain** — commit fully or keep it simple throughout
+- **Don't create text-only slides** — add images, icons, charts, or visual elements; avoid plain title + bullets
+- **Don't forget text box padding** — when aligning lines or shapes with text edges, set `margin: 0` on the text box or offset the shape to account for padding
+- **Don't use low-contrast elements** — icons AND text need strong contrast against the background; avoid light text on light backgrounds or dark text on dark backgrounds
+- **NEVER use accent lines under titles** — these are a hallmark of AI-generated slides; use whitespace or background color instead
+
+---
+
+## QA (Required)
+
+**Assume there are problems. Your job is to find them.**
+
+Your first render is almost never correct. Approach QA as a bug hunt, not a confirmation step. If you found zero issues on first inspection, you weren't looking hard enough.
+
+### Content QA
+
+```bash
+python -m markitdown output.pptx
+```
+
+Check for missing content, typos, wrong order.
+
+**When using templates, check for leftover placeholder text:**
+
+```bash
+python -m markitdown output.pptx | grep -iE "xxxx|lorem|ipsum|this.*(page|slide).*layout"
+```
+
+If grep returns results, fix them before declaring success.
+
+### Visual QA
+
+**⚠️ USE SUBAGENTS** — even for 2-3 slides. You've been staring at the code and will see what you expect, not what's there. Subagents have fresh eyes.
+
+Convert slides to images (see [Converting to Images](#converting-to-images)), then use this prompt:
+
+```
+Visually inspect these slides. Assume there are issues — find them.
+
+Look for:
+- Overlapping elements (text through shapes, lines through words, stacked elements)
+- Text overflow or cut off at edges/box boundaries
+- Decorative lines positioned for single-line text but title wrapped to two lines
+- Source citations or footers colliding with content above
+- Elements too close (< 0.3" gaps) or cards/sections nearly touching
+- Uneven gaps (large empty area in one place, cramped in another)
+- Insufficient margin from slide edges (< 0.5")
+- Columns or similar elements not aligned consistently
+- Low-contrast text (e.g., light gray text on cream-colored background)
+- Low-contrast icons (e.g., dark icons on dark backgrounds without a contrasting circle)
+- Text boxes too narrow causing excessive wrapping
+- Leftover placeholder content
+
+For each slide, list issues or areas of concern, even if minor.
+
+Read and analyze these images:
+1. /path/to/slide-01.jpg (Expected: [brief description])
+2. /path/to/slide-02.jpg (Expected: [brief description])
+
+Report ALL issues found, including minor ones.
+```
+
+### Verification Loop
+
+1. Generate slides → Convert to images → Inspect
+2. **List issues found** (if none found, look again more critically)
+3. Fix issues
+4. **Re-verify affected slides** — one fix often creates another problem
+5. Repeat until a full pass reveals no new issues
+
+**Do not declare success until you've completed at least one fix-and-verify cycle.**
+
+---
+
+## Converting to Images
+
+Convert presentations to individual slide images for visual inspection:
+
+```bash
+python .opencode/skills/pptx/scripts/office/soffice.py --headless --convert-to pdf outputs/output.pptx
+pdftoppm -jpeg -r 150 outputs/output.pdf outputs/slide
+```
+
+This creates `slide-01.jpg`, `slide-02.jpg`, etc.
+
+To re-render specific slides after fixes:
+
+```bash
+pdftoppm -jpeg -r 150 -f N -l N outputs/output.pdf outputs/slide-fixed
+```
+
+---
+
+## Dependencies
+
+- `pip install "markitdown[pptx]"` - text extraction
+- `pip install Pillow` - thumbnail grids
+- `npm install -g pptxgenjs` - creating from scratch
+- LibreOffice (`soffice`) - PDF conversion (auto-configured for sandboxed environments via `.opencode/skills/pptx/scripts/office/soffice.py`)
+- Poppler (`pdftoppm`) - PDF to images

+# Editing Presentations
+
+> **Path convention**: All commands run from the **session workspace**. Never `cd` into the skill directory. Prefix all skill scripts with `.opencode/skills/pptx/`. All generated files go in `outputs/`.
+
+## Template-Based Workflow
+
+When using an existing presentation as a template:
+
+1. **Analyze existing slides**:
+   ```bash
+   python .opencode/skills/pptx/scripts/thumbnail.py template.pptx outputs/thumbnails
+   python -m markitdown template.pptx
+   ```
+   Review `outputs/thumbnails.jpg` to see layouts, and markitdown output to see placeholder text.
+
+2. **Plan slide mapping**: For each content section, choose a template slide.
+
+   ⚠️ **USE VARIED LAYOUTS** — monotonous presentations are a common failure mode. Don't default to basic title + bullet slides. Actively seek out:
+   - Multi-column layouts (2-column, 3-column)
+   - Image + text combinations
+   - Full-bleed images with text overlay
+   - Quote or callout slides
+   - Section dividers
+   - Stat/number callouts
+   - Icon grids or icon + text rows
+
+   **Avoid:** Repeating the same text-heavy layout for every slide.
+
+   Match content type to layout style (e.g., key points → bullet slide, team info → multi-column, testimonials → quote slide).
+
+3. **Unpack**: `python .opencode/skills/pptx/scripts/office/unpack.py template.pptx outputs/unpacked/`
+
+4. **Build presentation** (do this yourself, not with subagents):
+   - Delete unwanted slides (remove from `<p:sldIdLst>`)
+   - Duplicate slides you want to reuse (`add_slide.py`)
+   - Reorder slides in `<p:sldIdLst>`
+   - **Complete all structural changes before step 5**
+
+5. **Edit content**: Update text in each `slide{N}.xml`.
+   **Use subagents here if available** — slides are separate XML files, so subagents can edit in parallel.
+
+6. **Clean**: `python .opencode/skills/pptx/scripts/clean.py outputs/unpacked/`
+
+7. **Pack**: `python .opencode/skills/pptx/scripts/office/pack.py outputs/unpacked/ outputs/output.pptx --original template.pptx`
+
+---
+
+## Scripts
+
+| Script | Purpose |
+|--------|---------|
+| `unpack.py` | Extract and pretty-print PPTX |
+| `add_slide.py` | Duplicate slide or create from layout |
+| `clean.py` | Remove orphaned files |
+| `pack.py` | Repack with validation |
+| `thumbnail.py` | Create visual grid of slides |
+
+### unpack.py
+
+```bash
+python .opencode/skills/pptx/scripts/office/unpack.py input.pptx outputs/unpacked/
+```
+
+Extracts PPTX, pretty-prints XML, escapes smart quotes.
+
+### add_slide.py
+
+```bash
+python .opencode/skills/pptx/scripts/add_slide.py outputs/unpacked/ slide2.xml      # Duplicate slide
+python .opencode/skills/pptx/scripts/add_slide.py outputs/unpacked/ slideLayout2.xml # From layout
+```
+
+Prints `<p:sldId>` to add to `<p:sldIdLst>` at desired position.
+
+### clean.py
+
+```bash
+python .opencode/skills/pptx/scripts/clean.py outputs/unpacked/
+```
+
+Removes slides not in `<p:sldIdLst>`, unreferenced media, orphaned rels.
+
+### pack.py
+
+```bash
+python .opencode/skills/pptx/scripts/office/pack.py outputs/unpacked/ outputs/output.pptx --original input.pptx
+```
+
+Validates, repairs, condenses XML, re-encodes smart quotes.
+
+### thumbnail.py
+
+```bash
+python .opencode/skills/pptx/scripts/thumbnail.py input.pptx outputs/thumbnails [--cols N]
+```
+
+Creates `outputs/thumbnails.jpg` with slide filenames as labels. Default 3 columns, max 12 per grid.
+
+**Use for template analysis only** (choosing layouts). For visual QA, use `soffice` + `pdftoppm` to create full-resolution individual slide images—see SKILL.md.
+
+---
+
+## Slide Operations
+
+Slide order is in `outputs/unpacked/ppt/presentation.xml` → `<p:sldIdLst>`.
+
+**Reorder**: Rearrange `<p:sldId>` elements.
+
+**Delete**: Remove `<p:sldId>`, then run `clean.py`.
+
+**See available layouts**: `ls outputs/unpacked/ppt/slideLayouts/`
+
+**Add**: Use `add_slide.py`. Never manually copy slide files—the script handles notes references, Content_Types.xml, and relationship IDs that manual copying misses.
+
+---
+
+## Editing Content
+
+**Subagents:** If available, use them here (after completing step 4). Each slide is a separate XML file, so subagents can edit in parallel. In your prompt to subagents, include:
+- The slide file path(s) to edit
+- **"Use the Edit tool for all changes"**
+- The formatting rules and common pitfalls below
+
+For each slide:
+1. Read the slide's XML
+2. Identify ALL placeholder content—text, images, charts, icons, captions
+3. Replace each placeholder with final content
+
+**Use the Edit tool, not sed or Python scripts.** The Edit tool forces specificity about what to replace and where, yielding better reliability.
+
+### Formatting Rules
+
+- **Bold all headers, subheadings, and inline labels**: Use `b="1"` on `<a:rPr>`. This includes:
+  - Slide titles
+  - Section headers within a slide
+  - Inline labels like (e.g.: "Status:", "Description:") at the start of a line
+- **Never use unicode bullets (•)**: Use proper list formatting with `<a:buChar>` or `<a:buAutoNum>`
+- **Bullet consistency**: Let bullets inherit from the layout. Only specify `<a:buChar>` or `<a:buNone>`.
+
+---
+
+## Common Pitfalls
+
+### Template Adaptation
+
+When source content has fewer items than the template:
+- **Remove excess elements entirely** (images, shapes, text boxes), don't just clear text
+- Check for orphaned visuals after clearing text content
+- Run visual QA to catch mismatched counts
+
+When replacing text with different length content:
+- **Shorter replacements**: Usually safe
+- **Longer replacements**: May overflow or wrap unexpectedly
+- Test with visual QA after text changes
+- Consider truncating or splitting content to fit the template's design constraints
+
+**Template slots ≠ Source items**: If template has 4 team members but source has 3 users, delete the 4th member's entire group (image + text boxes), not just the text.
+
+### Multi-Item Content
+
+If source has multiple items (numbered lists, multiple sections), create separate `<a:p>` elements for each — **never concatenate into one string**.
+
+**❌ WRONG** — all items in one paragraph:
+```xml
+<a:p>
+  <a:r><a:rPr .../><a:t>Step 1: Do the first thing. Step 2: Do the second thing.</a:t></a:r>
+</a:p>
+```
+
+**✅ CORRECT** — separate paragraphs with bold headers:
+```xml
+<a:p>
+  <a:pPr algn="l"><a:lnSpc><a:spcPts val="3919"/></a:lnSpc></a:pPr>
+  <a:r><a:rPr lang="en-US" sz="2799" b="1" .../><a:t>Step 1</a:t></a:r>
+</a:p>
+<a:p>
+  <a:pPr algn="l"><a:lnSpc><a:spcPts val="3919"/></a:lnSpc></a:pPr>
+  <a:r><a:rPr lang="en-US" sz="2799" .../><a:t>Do the first thing.</a:t></a:r>
+</a:p>
+<a:p>
+  <a:pPr algn="l"><a:lnSpc><a:spcPts val="3919"/></a:lnSpc></a:pPr>
+  <a:r><a:rPr lang="en-US" sz="2799" b="1" .../><a:t>Step 2</a:t></a:r>
+</a:p>
+<!-- continue pattern -->
+```
+
+Copy `<a:pPr>` from the original paragraph to preserve line spacing. Use `b="1"` on headers.
+
+### Smart Quotes
+
+Handled automatically by unpack/pack. But the Edit tool converts smart quotes to ASCII.
+
+**When adding new text with quotes, use XML entities:**
+
+```xml
+<a:t>the &#x201C;Agreement&#x201D;</a:t>
+```
+
+| Character | Name | Unicode | XML Entity |
+|-----------|------|---------|------------|
+| `“` | Left double quote | U+201C | `&#x201C;` |
+| `”` | Right double quote | U+201D | `&#x201D;` |
+| `‘` | Left single quote | U+2018 | `&#x2018;` |
+| `’` | Right single quote | U+2019 | `&#x2019;` |
+
+### Other
+
+- **Whitespace**: Use `xml:space="preserve"` on `<a:t>` with leading/trailing spaces
+- **XML parsing**: Use `defusedxml.minidom`, not `xml.etree.ElementTree` (corrupts namespaces)

+
+let pres = new pptxgen();
+pres.layout = 'LAYOUT_16x9';  // or 'LAYOUT_16x10', 'LAYOUT_4x3', 'LAYOUT_WIDE'
+pres.author = 'Your Name';
+pres.title = 'Presentation Title';

+
+## Layout Dimensions
+

+- `LAYOUT_16x9`: 10" × 5.625" (default)
+- `LAYOUT_16x10`: 10" × 6.25"
+- `LAYOUT_4x3`: 10" × 7.5"
+- `LAYOUT_WIDE`: 13.3" × 7.5"
+
+---
+
+## Text & Formatting
+
+```javascript
+// Basic text
+slide.addText("Simple Text", {
+  x: 1, y: 1, w: 8, h: 2, fontSize: 24, fontFace: "Arial",
+  color: "363636", bold: true, align: "center", valign: "middle"
+});
+
+// Character spacing (use charSpacing, not letterSpacing which is silently ignored)
+slide.addText("SPACED TEXT", { x: 1, y: 1, w: 8, h: 1, charSpacing: 6 });
+
+// Rich text arrays
+slide.addText([
+  { text: "Bold ", options: { bold: true } },
+  { text: "Italic ", options: { italic: true } }
+], { x: 1, y: 3, w: 8, h: 1 });
+
+// Multi-line text (requires breakLine: true)
+slide.addText([
+  { text: "Line 1", options: { breakLine: true } },
+  { text: "Line 2", options: { breakLine: true } },
+  { text: "Line 3" }  // Last item doesn't need breakLine
+], { x: 0.5, y: 0.5, w: 8, h: 2 });
+
+// Text box margin (internal padding)
+slide.addText("Title", {
+  x: 0.5, y: 0.3, w: 9, h: 0.6,
+  margin: 0  // Use 0 when aligning text with other elements like shapes or icons
+});
+```
+
+**Tip:** Text boxes have internal margin by default. Set `margin: 0` when you need text to align precisely with shapes, lines, or icons at the same x-position.
+
+---
+
+## Lists & Bullets
+
+```javascript
+// ✅ CORRECT: Multiple bullets
+slide.addText([
+  { text: "First item", options: { bullet: true, breakLine: true } },

+], { x: 0.5, y: 0.5, w: 8, h: 3 });
+
+// ❌ WRONG: Never use unicode bullets

+## Shapes
+
+```javascript
+slide.addShape(pres.shapes.RECTANGLE, {
+  x: 0.5, y: 0.8, w: 1.5, h: 3.0,
+  fill: { color: "FF0000" }, line: { color: "000000", width: 2 }
+});
+
+slide.addShape(pres.shapes.OVAL, { x: 4, y: 1, w: 2, h: 2, fill: { color: "0000FF" } });
+
+slide.addShape(pres.shapes.LINE, {
+  x: 1, y: 3, w: 5, h: 0, line: { color: "FF0000", width: 3, dashType: "dash" }
+});
+
+// With transparency
+slide.addShape(pres.shapes.RECTANGLE, {
+  x: 1, y: 1, w: 3, h: 2,
+  fill: { color: "0088CC", transparency: 50 }
+});
+
+// Rounded rectangle (rectRadius only works with ROUNDED_RECTANGLE, not RECTANGLE)
+// ⚠️ Don't pair with rectangular accent overlays — they won't cover rounded corners. Use RECTANGLE instead.
+slide.addShape(pres.shapes.ROUNDED_RECTANGLE, {
+  x: 1, y: 1, w: 3, h: 2,
+  fill: { color: "FFFFFF" }, rectRadius: 0.1
+});
+
+// With shadow
+slide.addShape(pres.shapes.RECTANGLE, {
+  x: 1, y: 1, w: 3, h: 2,
+  fill: { color: "FFFFFF" },
+  shadow: { type: "outer", color: "000000", blur: 6, offset: 2, angle: 135, opacity: 0.15 }
+});
+```
+
+Shadow options:
+
+| Property | Type | Range | Notes |
+|----------|------|-------|-------|
+| `type` | string | `"outer"`, `"inner"` | |
+| `color` | string | 6-char hex (e.g. `"000000"`) | No `#` prefix, no 8-char hex — see Common Pitfalls |
+| `blur` | number | 0-100 pt | |
+| `offset` | number | 0-200 pt | **Must be non-negative** — negative values corrupt the file |
+| `angle` | number | 0-359 degrees | Direction the shadow falls (135 = bottom-right, 270 = upward) |
+| `opacity` | number | 0.0-1.0 | Use this for transparency, never encode in color string |
+
+To cast a shadow upward (e.g. on a footer bar), use `angle: 270` with a positive offset — do **not** use a negative offset.
+
+**Note**: Gradient fills are not natively supported. Use a gradient image as a background instead.

+
+## Images
+
+### Image Sources
+
+```javascript
+// From file path
+slide.addImage({ path: "images/chart.png", x: 1, y: 1, w: 5, h: 3 });
+
+// From URL
+slide.addImage({ path: "https://example.com/image.jpg", x: 1, y: 1, w: 5, h: 3 });
+
+// From base64 (faster, no file I/O)
+slide.addImage({ data: "image/png;base64,iVBORw0KGgo...", x: 1, y: 1, w: 5, h: 3 });
+```
+
+### Image Options
+
+```javascript
+slide.addImage({
+  path: "image.png",
+  x: 1, y: 1, w: 5, h: 3,
+  rotate: 45,              // 0-359 degrees
+  rounding: true,          // Circular crop
+  transparency: 50,        // 0-100
+  flipH: true,             // Horizontal flip
+  flipV: false,            // Vertical flip
+  altText: "Description",  // Accessibility
+  hyperlink: { url: "https://example.com" }
+});
+```
+
+### Image Sizing Modes
+
+```javascript
+// Contain - fit inside, preserve ratio
+{ sizing: { type: 'contain', w: 4, h: 3 } }
+
+// Cover - fill area, preserve ratio (may crop)
+{ sizing: { type: 'cover', w: 4, h: 3 } }
+
+// Crop - cut specific portion
+{ sizing: { type: 'crop', x: 0.5, y: 0.5, w: 2, h: 2 } }
+```
+
+### Calculate Dimensions (preserve aspect ratio)
+
+```javascript
+const origWidth = 1978, origHeight = 923, maxHeight = 3.0;
+const calcWidth = maxHeight * (origWidth / origHeight);
+const centerX = (10 - calcWidth) / 2;
+
+slide.addImage({ path: "image.png", x: centerX, y: 1.2, w: calcWidth, h: maxHeight });
+```
+
+### Supported Formats
+
+- **Standard**: PNG, JPG, GIF (animated GIFs work in Microsoft 365)
+- **SVG**: Works in modern PowerPoint/Microsoft 365
+
+---
+
+## Icons
+
+Use react-icons to generate SVG icons, then rasterize to PNG for universal compatibility.
+
+### Setup
+
+```javascript
+const React = require("react");
+const ReactDOMServer = require("react-dom/server");
+const sharp = require("sharp");
+const { FaCheckCircle, FaChartLine } = require("react-icons/fa");
+
+function renderIconSvg(IconComponent, color = "#000000", size = 256) {
+  return ReactDOMServer.renderToStaticMarkup(
+    React.createElement(IconComponent, { color, size: String(size) })
+  );
+}
+
+async function iconToBase64Png(IconComponent, color, size = 256) {
+  const svg = renderIconSvg(IconComponent, color, size);
+  const pngBuffer = await sharp(Buffer.from(svg)).png().toBuffer();
+  return "image/png;base64," + pngBuffer.toString("base64");
+}
+```
+
+### Add Icon to Slide
+
+```javascript
+const iconData = await iconToBase64Png(FaCheckCircle, "#4472C4", 256);
+
+slide.addImage({
+  data: iconData,
+  x: 1, y: 1, w: 0.5, h: 0.5  // Size in inches
+});
+```
+
+**Note**: Use size 256 or higher for crisp icons. The size parameter controls the rasterization resolution, not the display size on the slide (which is set by `w` and `h` in inches).
+
+### Icon Libraries
+
+Install: `npm install -g react-icons react react-dom sharp`
+
+Popular icon sets in react-icons:
+- `react-icons/fa` - Font Awesome
+- `react-icons/md` - Material Design
+- `react-icons/hi` - Heroicons
+- `react-icons/bi` - Bootstrap Icons
+
+---
+
+## Slide Backgrounds
+
+```javascript
+// Solid color
+slide.background = { color: "F1F1F1" };
+
+// Color with transparency
+slide.background = { color: "FF3399", transparency: 50 };
+
+// Image from URL
+slide.background = { path: "https://example.com/bg.jpg" };
+
+// Image from base64
+slide.background = { data: "image/png;base64,iVBORw0KGgo..." };
+```
+
+---
+
+## Tables
+
+```javascript
+slide.addTable([
+  ["Header 1", "Header 2"],
+  ["Cell 1", "Cell 2"]
+], {
+  x: 1, y: 1, w: 8, h: 2,
+  border: { pt: 1, color: "999999" }, fill: { color: "F1F1F1" }
+});
+
+// Advanced with merged cells
+let tableData = [
+  [{ text: "Header", options: { fill: { color: "6699CC" }, color: "FFFFFF", bold: true } }, "Cell"],
+  [{ text: "Merged", options: { colspan: 2 } }]
+];
+slide.addTable(tableData, { x: 1, y: 3.5, w: 8, colW: [4, 4] });
+```
+
+---
+
+## Charts
+
+```javascript
+// Bar chart
+slide.addChart(pres.charts.BAR, [{
+  name: "Sales", labels: ["Q1", "Q2", "Q3", "Q4"], values: [4500, 5500, 6200, 7100]
+}], {
+  x: 0.5, y: 0.6, w: 6, h: 3, barDir: 'col',
+  showTitle: true, title: 'Quarterly Sales'
+});
+
+// Line chart
+slide.addChart(pres.charts.LINE, [{
+  name: "Temp", labels: ["Jan", "Feb", "Mar"], values: [32, 35, 42]
+}], { x: 0.5, y: 4, w: 6, h: 3, lineSize: 3, lineSmooth: true });
+
+// Pie chart
+slide.addChart(pres.charts.PIE, [{
+  name: "Share", labels: ["A", "B", "Other"], values: [35, 45, 20]
+}], { x: 7, y: 1, w: 5, h: 4, showPercent: true });
+```
+
+### Better-Looking Charts
+
+Default charts look dated. Apply these options for a modern, clean appearance:
+
+```javascript
+slide.addChart(pres.charts.BAR, chartData, {
+  x: 0.5, y: 1, w: 9, h: 4, barDir: "col",
+
+  // Custom colors (match your presentation palette)
+  chartColors: ["0D9488", "14B8A6", "5EEAD4"],
+
+  // Clean background
+  chartArea: { fill: { color: "FFFFFF" }, roundedCorners: true },
+
+  // Muted axis labels
+  catAxisLabelColor: "64748B",
+  valAxisLabelColor: "64748B",
+
+  // Subtle grid (value axis only)
+  valGridLine: { color: "E2E8F0", size: 0.5 },
+  catGridLine: { style: "none" },
+
+  // Data labels on bars
+  showValue: true,
+  dataLabelPosition: "outEnd",
+  dataLabelColor: "1E293B",
+
+  // Hide legend for single series
+  showLegend: false,
+});
+```
+
+**Key styling options:**
+- `chartColors: [...]` - hex colors for series/segments
+- `chartArea: { fill, border, roundedCorners }` - chart background
+- `catGridLine/valGridLine: { color, style, size }` - grid lines (`style: "none"` to hide)
+- `lineSmooth: true` - curved lines (line charts)
+- `legendPos: "r"` - legend position: "b", "t", "l", "r", "tr"
+
+---
+
+## Slide Masters
+
+```javascript
+pres.defineSlideMaster({
+  title: 'TITLE_SLIDE', background: { color: '283A5E' },
+  objects: [{
+    placeholder: { options: { name: 'title', type: 'title', x: 1, y: 2, w: 8, h: 2 } }
+  }]
+});
+
+let titleSlide = pres.addSlide({ masterName: "TITLE_SLIDE" });
+titleSlide.addText("My Title", { placeholder: "title" });
+```
+
+---
+
+## Common Pitfalls
+
+⚠️ These issues cause file corruption, visual bugs, or broken output. Avoid them.
+
+1. **NEVER use "#" with hex colors** - causes file corruption
+   ```javascript
+   color: "FF0000"      // ✅ CORRECT
+   color: "#FF0000"     // ❌ WRONG
+   ```
+
+2. **NEVER encode opacity in hex color strings** - 8-char colors (e.g., `"00000020"`) corrupt the file. Use the `opacity` property instead.
+   ```javascript
+   shadow: { type: "outer", blur: 6, offset: 2, color: "00000020" }          // ❌ CORRUPTS FILE
+   shadow: { type: "outer", blur: 6, offset: 2, color: "000000", opacity: 0.12 }  // ✅ CORRECT
+   ```
+
+3. **Use `bullet: true`** - NEVER unicode symbols like "•" (creates double bullets)
+
+4. **Use `breakLine: true`** between array items or text runs together
+
+5. **Avoid `lineSpacing` with bullets** - causes excessive gaps; use `paraSpaceAfter` instead
+
+6. **Each presentation needs fresh instance** - don't reuse `pptxgen()` objects
+
+7. **NEVER reuse option objects across calls** - PptxGenJS mutates objects in-place (e.g. converting shadow values to EMU). Sharing one object between multiple calls corrupts the second shape.
+   ```javascript
+   const shadow = { type: "outer", blur: 6, offset: 2, color: "000000", opacity: 0.15 };
+   slide.addShape(pres.shapes.RECTANGLE, { shadow, ... });  // ❌ second call gets already-converted values
+   slide.addShape(pres.shapes.RECTANGLE, { shadow, ... });
+
+   const makeShadow = () => ({ type: "outer", blur: 6, offset: 2, color: "000000", opacity: 0.15 });
+   slide.addShape(pres.shapes.RECTANGLE, { shadow: makeShadow(), ... });  // ✅ fresh object each time
+   slide.addShape(pres.shapes.RECTANGLE, { shadow: makeShadow(), ... });
+   ```
+
+8. **Don't use `ROUNDED_RECTANGLE` with accent borders** - rectangular overlay bars won't cover rounded corners. Use `RECTANGLE` instead.
+   ```javascript
+   // ❌ WRONG: Accent bar doesn't cover rounded corners
+   slide.addShape(pres.shapes.ROUNDED_RECTANGLE, { x: 1, y: 1, w: 3, h: 1.5, fill: { color: "FFFFFF" } });
+   slide.addShape(pres.shapes.RECTANGLE, { x: 1, y: 1, w: 0.08, h: 1.5, fill: { color: "0891B2" } });
+
+   // ✅ CORRECT: Use RECTANGLE for clean alignment
+   slide.addShape(pres.shapes.RECTANGLE, { x: 1, y: 1, w: 3, h: 1.5, fill: { color: "FFFFFF" } });
+   slide.addShape(pres.shapes.RECTANGLE, { x: 1, y: 1, w: 0.08, h: 1.5, fill: { color: "0891B2" } });
+   ```
+

+
+    Note that local names in this namespace are intended to be defined

+    following names are currently defined in this namespace and should
+    not be used with conflicting semantics by any Working Group,
+    specification, or document instance:
+
+    base (as an attribute name): denotes an attribute whose value
+         provides a URI to be used as the base for interpreting any
+         relative URIs in the scope of the element on which it
+         appears; its value is inherited.  This name is reserved
+         by virtue of its definition in the XML Base specification.
+
+    lang (as an attribute name): denotes an attribute whose value
+         is a language code for the natural language of the content of
+         any element; its value is inherited.  This name is reserved
+         by virtue of its definition in the XML specification.
+  
+    space (as an attribute name): denotes an attribute whose
+         value is a keyword indicating what whitespace processing
+         discipline is intended for the content of the element; its
+         value is inherited.  This name is reserved by virtue of its
+         definition in the XML specification.
+
+    Father (in any context at all): denotes Jon Bosak, the chair of 
+         the original XML Working Group.  This name is reserved by 
+         the following decision of the W3C XML Plenary and 
+         XML Coordination groups:

+  <xs:documentation>This schema defines attributes and an attribute group
+        suitable for use by
+        schemas wishing to allow xml:base, xml:lang or xml:space attributes
+        on elements they define.
+
+        To enable this, such a schema must import this schema
+        for the XML namespace, e.g. as follows:
+        &lt;schema . . .>
+         . . .
+         &lt;import namespace="http://www.w3.org/XML/1998/namespace"
+                    schemaLocation="http://www.w3.org/2001/03/xml.xsd"/>
+
+        Subsequently, qualified reference to any of the attributes
+        or the group defined below will have the desired effect, e.g.
+
+        &lt;type . . .>
+         . . .
+         &lt;attributeGroup ref="xml:specialAttrs"/>
+ 
+         will define a type which will schema-validate an instance
+         element with any of those attributes</xs:documentation>

+  <xs:documentation>In keeping with the XML Schema WG's standard versioning
+   policy, this schema document will persist at
+   http://www.w3.org/2001/03/xml.xsd.
+   At the date of issue it can also be found at
+   http://www.w3.org/2001/xml.xsd.
+   The schema document at that URI may however change in the future,
+   in order to remain compatible with the latest version of XML Schema
+   itself.  In other words, if the XML Schema namespace changes, the version
+   of this document at

+"""Create thumbnail grids from PowerPoint presentation slides.
+
+Creates a grid layout of slide thumbnails for quick visual analysis.
+Labels each thumbnail with its XML filename (e.g., slide1.xml).
+Hidden slides are shown with a placeholder pattern.
+
+Usage:
+    python thumbnail.py input.pptx [output_prefix] [--cols N]
+
+Examples:
+    python thumbnail.py presentation.pptx
+    # Creates: thumbnails.jpg
+
+    python thumbnail.py template.pptx grid --cols 4
+    # Creates: grid.jpg (or grid-1.jpg, grid-2.jpg for large decks)
