Create brand tokens for apps and documents

Create and use brand.yml files for consistent app/document branding

Design system owners ensuring Shiny apps and Quarto documents use consistent brand tokens without duplicating CSS.

• · Brand guidelines: colors (primary, secondary, semantic), fonts (families, sizes), logos, company meta
• · Existing _brand.yml file path (for modification)
• · Brand context: company name, links, social

• · YAML _brand.yml file with color palette, typography, logo paths, meta
• · Specification reference to brand-yml-spec.md
• · Integration instructions for Shiny (R/Python), Quarto, R Markdown

• · YAML-compliant editor
• · Shiny (R or Python) or Quarto for consumption

• · Brand guidelines document available
• · Logo files at known relative paths
• · Google Fonts or local font sources specified

• · Hex color format invalid (missing # or uppercase) → parsing silent failure
• · Font family referenced before defined in palette → undefined color reference
• · File paths relative instead of absolute → images/fonts not found at runtime

• · Decision tree with 7 explicit paths
• · Step-by-step file creation from brand guidelines
• · Minimum viable YAML example + progressively enhanced versions
• · Named best practices: hex format, lowercase hyphens, color palette before reference
