Uses design tokens for brand-consistent placeholders. The script automatically looks for CSS files in common locations and extracts color tokens.
Token Mapping:
| Placeholder Color | Tokens Searched |
|---|---|
| Background | --background-alt, --background-main, --surface-color |
| Stroke | --border-color, --border-light |
| Text | --text-muted, --text-color |
| Accent | --primary-color, --primary, --accent-color |
| Accent Text | --text-inverted, --primary-text |
Auto-detection paths:
src/styles/main.csssrc/styles/_tokens.css.assets/styles/main.css.claude/styles/main.css# Auto-detect CSS file
node .claude/scripts/generate-placeholder.js --type brand --label "Product" --preset product
# Specify CSS file explicitly
node .claude/scripts/generate-placeholder.js --type brand --label "Hero" --size 1200x400 --tokens src/styles/main.css
Example output:
<svg xmlns="http://www.w3.org/2000/svg" viewBox="0 0 400 400"
role="img" aria-label="Product Shot placeholder">

<rect width="400" height="400" fill="#f8fafc"/>

For quick prototyping, use inline data URIs:
<img src="data:image/svg+xml,..." alt="Placeholder"/>
Generate with:
node .claude/scripts/generate-placeholder.js --type simple --size 200x200 --inline
All placeholders MUST include:
