yuanfang-design

Shared design library providing:

• base.css — 30+ token CSS variables (colors, fonts, sizes, space, radius, shadow, decor, feature flags)
• themes/ — 12 theme overrides, each as a single CSS file using [data-theme="..."] selectors
• layout-types/ — Reusable HTML blocks (cover.html, future bullets/kpi-grid/etc.)
• showcase/ — Visual QA tool: 12 themes × 6 platforms = 72 iframes in a grid
• references/authoring-guide.md — Rules for adding new themes/layout-types

When to use

Use this skill when:

• The user wants to add a new visual style → create a new theme file
• The user wants to add a new layout type (e.g., bullets, kpi-grid) → create new HTML block
• The user wants to view all themes/layouts at once → open the showcase
• The user wants to understand the design system → read authoring-guide.md

How themes work

A theme is a single CSS file that overrides base.css tokens:

[data-theme="dark-gold"] {
  --bg: #1A1A2E;
  --text: #F5E6D3;
  --accent: #E2B714;
  /* ... */
}

The cover.html layout-type references tokens only. Swapping the theme = reskinning the entire layout.

How to add a new theme

1. Copy themes/_template.css to themes/.css
2. Override tokens for: colors, fonts, sizes, decor, feature flags
3. Test: npm run render -- --theme --layout cover --platforms xiaohongshu-v
4. Update showcase/cover-showcase.html to include the new theme

How to add a new layout-type

1. Create layout-types/.html with {{}} placeholders for content
2. Add corresponding .layout- rules to base.css (or new file)
3. Test: npm run render -- --theme minimal-white --layout --platforms all
4. Add to showcase
