/* The landing page: a drafting sheet, after Luci Studio's blueprint home
   (kido-luci/luci-studio-frontend, HomePage.astro and home/): cream paper with
   a fine grid, hairline rules, numbered section heads in mono, large display
   headings. Its two accents are the mascot cubes' blue and orange
   (mobile/packages/features/today/.../cubes/cube_drawing.dart). Light only,
   while the app's screens are not settled (docs/project-brief.md §3).
   Every page of the site uses this sheet: the landing, the documents, the
