## Editing Workflow

**Read [editing.md](editing.md) for full details.**

1. Analyze template with `thumbnail.py`
2. Unpack → manipulate slides → edit content → clean → pack

## 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 h
