# /socialforge:render-carousels — Carousel Renderer

Produce multi-slide carousel images from HTML/CSS templates using Playwright headless rendering.

## Supported Templates

| Template | Slides | Best For |
|----------|--------|----------|
| generic-8slide | 8 | General purpose |
| comparison-10slide | 10 | Feature comparisons |
| case-study-10slide | 10 | Client success stories |
| tips-5slide | 5 | Quick tips |
| playbook-8slide | 8 | Step-by-step playbooks |
| recap-6slide | 6 | Event/month recaps |
| data-infographic-6slide | 6 | Data-driven infographics |
| quote-card-single | 1 | Single quote cards |

## Process

1. Select template based on post's `carousel_type`
2. For each slide:
   - Inject content (title, body, data points, statistics)
   - Apply brand colors via CSS variables (--brand-primary, --brand-secondary, etc.)
   - Apply brand fonts
   - If slide needs background image: generate or compose via image-compositor
3. Render each slide via Playwright (headless Chromium → PNG, 1080x1080)
4. Show first and last slide to user for approval
5. Compile all slides into PDF (for LinkedIn document upload)
6. Resize slides for other platforms if needed

## Rules
- First slide = hook/title with brand identity
- Last slide = CTA with brand logo and contact info
- Max text per slide: 40 words (LinkedIn) | 25 words (Instagram)
- All slides use brand fonts and colors from brand-config.json
- Slide dimensions: 1080x1080 default (configurable per brand)

## Scripts Used
- render_carousel.py — Playwright HTML→PNG rendering

## Timeout & Fallback
- Per-slide render: 15-second timeout. If Playwright hangs, retry without custom fonts.
- Full carousel: 3-minute timeout for 10 slides.
- If Playwright unavailable: flag for manual rendering, save populated HTML for export.
