Analyze template with `thumbnail.py`\n2. Unpack → manipulate slides → edit content → clean → pack\n\n---\n\n## Creating from Scratch\n\n**Read [pptxgenjs.md](pptxgenjs.md) for full details.**\n\nUse when no template or reference presentation is available.\n\n---\n\n## Design Ideas\n\n**Don't create boring slides.** Plain bullets on a white background won't impress anyone. Consider ideas from this list for each slide.\n\n### Before Starting\n\n- **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.\n- **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.\n- **Dark/light contrast**: Dark backgrounds for title + conclusion slides, light for content (\"sandwich\" structure). Or commit to dark throughout for a premium feel.\n- **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.\n\n### Color Palettes\n\nChoose colors that match your topic — don't default to generic blue. Use these palettes as inspiration:\n\n| Theme | Primary | Secondary | Accent |\n|-------|---------|-----------|--------|\n| **Midnight Executive** | `1E2761` (navy) | `CADCFC` (ice blue) | `FFFFFF` (white) |\n| **Forest & Moss** | `2C5F2D` (forest) | `97BC62` (moss) | `F5F5F5` (cream) |\n| **Coral Energy** | `F96167` (coral) | `F9E795` (gold) | `2F3C7E` (navy) |\n| **Warm Terracotta** | `B85042` (terracotta) | `E7E8D1` (sand) | `A7BEAE` (sage) |\n| **Ocean Gradient** | `065A82` (deep blue) | `1C7293` (teal) | `21295C` (midnight) |\n| **Charcoal Minimal** | `36454F` (charcoal) | `F2F2F2` (off-white) | `212121` (black) |\n| **Teal Trust** | `028090` (teal) | `00A896` (seafoam) | `02C39A` (mint) |\n| **Berry & Cream** | `6D2E46` (berry) | `A26769` (dusty rose) | `ECE2D0` (cream) |\n| **Sage Calm** | `84B59F` (sage) | `69A297` (eucalyptus) | `50808E` (slate) |\n| **Cherry Bold** | `990011` (cherry) | `FCF6F5` (off-white) | `2F3C7E` (navy) |\n\n### For Each Slide\n\n**Every slide needs a visual element** — image, chart, icon, or shape. Text-only slides are forgettable.\n\n**Layout options:**\n- Two-column (text left, illustration on right)\n- Icon + text rows (icon in colored circle, bold header, description below)\n- 2x2 or 2x3 grid (image on one side, grid of content blocks on other)\n- Half-bleed image (full left or right side) with content overlay\n\n**Data display:**\n- Large stat callouts (big numbers 60-72pt with small labels below)\n- Comparison columns (before/after, pros/cons, side-by-side options)\n- Timeline or process flow (numbered steps, arrows)\n\n**Visual polish:**\n- Icons in small colored circles next to section headers\n- Italic accent text for key stats or taglines\n\n### Typography\n\n**Choose an interesting font pairing** — don't default to Arial. Pick a header font with personality and pair it with a clean body font.\n\n| Header Font | Body Font |\n|-------------|-----------|\n| Georgia | Calibri |\n| Arial Black | Arial |\n| Calibri | Calibri Light |\n| Cambria | Calibri |\n| Trebuchet MS | Calibri |\n| Impact | Arial |\n| Palatino | Garamond |\n| Consolas | Calibri |\n\n| Element | Size |\n|---------|------|\n| Slide title | 36-44pt bold |\n| Section header | 20-24pt bold |\n| Body text | 14-16pt |\n| Captions | 10-12pt muted |\n\n### Spacing\n\n- 0.5\" minimum margins\n- 0.3-0.5\" between content blocks\n- Leave breathing room—don't fill every inch\n\n### Avoid (Common Mistakes)\n\n- **Don't repeat the same layout** — vary columns, cards, and callouts across slides\n- **Don't center body text** — left-align paragraphs and lists; center only titles\n- **Don't skimp on size contrast** — titles need 36pt+ to stand out from 14-16pt body\n- **Don't default to blue** — pick colors that reflect the specific topic\n- **Don't mix spacing randomly** — choose 0.3\" or 0.5\" gaps and use consistently\n- **Don't style one slide and leave the rest plain** — commit fully or keep it simple throughout\n- **Don't create text-only slides** — add images, icons, charts, or visual elements; avoid plain title + bullets\n- **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\n- **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\n- **NEVER use accent lines under titles** — these are a hallmark of AI-generated slides; use whitespace or background color instead\n\n---\n\n## QA (Required)\n\n**Assume there are problems. Your job is to find them.**\n\nYour 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.\n\n### Content QA\n\n```bash\npython -m markitdown output.pptx\n```\n\nCheck for missing content, typos, wrong order.\n\n**When using templates, check for leftover placeholder text:**\n\n```bash\npython -m markitdown output.pptx | grep -iE \"xxxx|lorem|ipsum|this.*(page|slide).*layout\"\n```\n\nIf grep returns results, fix them before declaring success.\n\n### Visual QA\n\n**⚠️ 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.\n\nConvert slides to images (see [Converting to Images](#converting-to-images)), then use this prompt:\n\n```\nVisually inspect these slides. Assume there are issues — find them.\n\nLook for:\n- Overlapping elements (text through shapes, lines through words, stacked elements)\n- Text overflow or cut off at edges/box boundaries\n- Decorative lines positioned for single-line text but title wrapped to two lines\n- Source citations or footers colliding with content above\n- Elements too close (< 0.3\" gaps) or cards/sections nearly touching\n- Uneven gaps (large empty area in one place, cramped in another)\n- Insufficient margin from slide edges (< 0.5\")\n- Columns or similar elements not aligned consistently\n- Low-contrast text (e.g., light gray text on cream-colored background)\n- Low-contrast icons (e.g., dark icons on dark backgrounds without a contrasting circle)\n- Text boxes too narrow causing excessive wrapping\n- Leftover placeholder content\n\nFor each slide, list issues or areas of concern, even if minor.\n\nRead and analyze these images:\n1. /path/to/slide-01.jpg (Expected: [brief description])\n2. /path/to/slide-02.jpg (Expected: [brief description])\n\nReport ALL issues found, including minor ones.\n```\n\n### Verification Loop\n\n1. Generate slides → Convert to images → Inspect\n2. **List issues found** (if none found, look again more critically)\n3. Fix issues\n4. **Re-verify affected slides** — one fix often creates another problem\n5. Repeat until a full pass reveals no new issues\n\n**Do not declare success until you've completed at least one fix-and-verify cycle.**\n\n---\n\n## Converting to Images\n\nConvert presentations to individual slide images for visual inspection:\n\n```bash\npython scripts/office/soffice.py --headless --convert-to pdf output.pptx\npdftoppm -jpeg -r 150 output.pdf slide\n```\n\nThis creates `slide-01.jpg`, `slide-02.jpg`, etc.\n\nTo re-render specific slides after fixes:\n\n```bash\npdftoppm -jpeg -r 150 -f N -l N output.pdf slide-fixed\n```\n\n---\n\n## Dependencies\n\n- `pip install \"markitdown[pptx]\"` - text extraction\n- `pip install Pillow` - thumbnail grids\n- `npm install -g pptxgenjs` - creating from scratch\n- LibreOffice (`soffice`) - PDF conversion (auto-configured for sandboxed environments via `scripts/office/soffice.py`)\n- Poppler (`pdftoppm`) - PDF to images\n"}
