   1. Tokens   2. Base & typography   3. Shell   4. Components
   5. Desk layout (wide screens)   6. Pocket notebook layout (narrow screens)

   Design intent: a personal travel diary, not a dashboard. Warm paper,
   dark ink, and two kinds of type: printed matter is set in Fraunces
   (a serif), and every annotation (dates, captions, stat labels, notes in
   the margin) is handwritten in Caveat. Per-trip colors arrive as
   --trip-color from PHP and are the only saturated marks on the page.

   Two intentional layouts, not one fluid one:
   the wide layout is a sheet of paper lying on a desk; the narrow layout
   is a pocket notebook with index tabs. The switch happens at 860px.

   Theming: the four knobs below (--paper, --card, --ink, --accent) can be
   overridden from the travel_settings table (theme_paper, theme_card,
   theme_ink, theme_accent); the layout template injects them as a :root
   style block. Everything else is derived with color-mix, so a new theme
   only needs those four values plus (optionally) trip_palette.

   Trip palette note: the default 8 trip colors live in PHP
   (helpers.php trip_palette()) and were machine-validated for CVD
   separation and >= 3:1 contrast against the default paper. If you change
   the paper or the palette, re-validate.

   HOUSE RULES (for future agents): never use em dashes, in copy or in
   comments. Do not add frameworks or CDN assets. Do not flatten the two
   layouts into one middle-ground design. See travel/docs/DESIGN.md.
