Document design

Create professional, print-ready HTML documents that export to PDF with customizable branding.

Brand configuration

Before creating documents, check for pdf-playground.local.md in the project root. If it is absent, check the legacy Claude Code path .claude/pdf-playground.local.md. If both exist, use only the project-root file. If neither exists, use sensible defaults or ask the user for their brand colors.

Reading brand config

Parse the selected config file's YAML frontmatter:

---
brand:
  name: "Organization Name"
  tagline: "Tagline"
  website: "https://example.com"
  email: "[email protected]"

colors:
  primary: "#CA3553"
  secondary: "#000000"
  background: "#FFFFFF"
  text: "#2d2a28"
  muted: "#666666"

fonts:
  heading: "Playfair Display"
  body: "Source Sans 3"
