# Slide Creator — HTML → PDF Presentations

Build slide decks as HTML, export to pixel-perfect 16:9 PDF via headless Chromium.

**Output format: PDF** — not Microsoft PowerPoint (.pptx). The PDF preserves exact layout, fonts, and colors across all devices.

## Why HTML → PDF

- CSS layout (Grid/Flexbox) is far more flexible than any PPT editor
- Full web typography, gradients, SVG, animations (print degrades gracefully)
- Git-friendly, reproducible, scriptable
- One command → PDF with exact 16:9 page dimensions

## Workflow

### 0. Identify Scenario (new)

Before any other step, identify the presentation scenario. Read `references/content-scaffolding.md` for full templates.

| Scenario keyword | Template to use |
|-----------------|----------------|
| pitch / investor / fundraising | `pitch-deck` |
| conference / keynote / summit / talk | `conference-keynote` |
| product launch / launch event | `product-launch` |
| report / research / analysis | `research-report` |
| (none of the above) | ask user which scenario fits best |

Each template defines: slide count, page titles, required content per page.

### 0.5 Bilingual Layout (if needed)

If the audience is bilingual (e.g. HK, Singapore, global Chinese conference), or the user mentions Chinese + English:
- Use the `bilingual` layout mode from `references/content-scaffolding.md`
- Heading: English (large) + Chinese subtitle (smaller, --text-muted)
- Body bullets: Chinese first, English parenthetical optional
- Avoid pure English-only decks for HK/TW/SG audiences

### 1. Plan the Deck

Define slide count and content per slide based on the scenario template. Each slide = one `<section class="slide">`.

### 1.5 Art Direction (run this before building)

> Run this step whenever the user hasn't provided a specific visual style.
> Read `skills/slide-creator/references/art-direction.md` for the full style taxonomy,
> CSS token templates, and style-brief output format.

**Step A — Ask 4 questions:**
1. Audience & setting: who is this for, and in what context (investors / internal team / public keynote)?
2. Mood keywords: how should the audience feel (authoritative / energetic / friendly / geeky-modern)?
3. Brand constraints: any required brand colors, logo, or fonts?
4. Reference material: any template references to align with (images, web links, existing deck screenshots)?

**Step B — Generate a visual style picker page:**
Do NOT present style options as text descriptions — users can't evaluate styles from words alone.

Reference handling rules:
- If user provides **image files/screenshots**: sample palette (primary/surface/accent), inspect layout density, corner radius, typography tone from the visual.
- If user provides **web URLs**: use `web_fetch` to extract design cues. **Critical — follow this extraction protocol to avoid misreading the style:**
  1. **Ignore the brand name / domain name** — never infer visual style from the product's industry or name (e.g. "Neo" does NOT mean neon, "Opera" does NOT mean European luxury).
  2. **Read copy tone & vocabulary** — the words used on the page reveal mood (e.g. "surgical precision", "quiet confidence" → restrained; "unleash", "radically" → bold/aggressive).
  3. **Extract explicit color vocabulary** — look for CSS keywords in the fetched text, or color names mentioned in body text / alt tags. Warm vs cool, light vs dark, muted vs saturated.
  4. **Infer layout density** — count words per section; sparse = editorial/luxury, dense = technical/functional.
  5. **Identify decorative
