   PERSONAL PROJECT TEMPLATE
   Layout, typography, and components for personal / editorial
   case studies. Uses CSS custom properties — each page must
   define its own palette in a local :root block:

     --brand       (accent colour — required)
     --paper       (page background)
     --paper-deep  (deeper section background)
     --paper-stage (stage / artifact background)
     --ink         (primary text)
     --ink-soft    (secondary text)
     --ink-faint   (tertiary / placeholder text)
     --rule        (divider colour)
     --closing-bg  (closing section background — optional, defaults to --ink)
