/* Layout, rhythm, and theme — visual primitives come from vendored modest-ui;
   everything site-specific lives here and nowhere else.

   Foundation rules (the /notes discipline):
   1. Text faces flow from tokens only: --mdst-font-text for prose,
      --font-display for editorial headings. No font-family on elements.
   2. Vertical spacing comes from the flow rules, not per-element margins.
   3. Every colour is a light-dark() token pair; the scheme follows the
      system preference or the <theme-toggle> override.

   Palette: ink on warm paper, two accents from Marcus's own world —
   squiggle cyan (links, focus, the mark itself) and hotdog red (the
   emphasis word, the pen nib, hovers). --cyan/--hot are the loud graphic
   values; --cyan-text is the darker cut that clears WCAG AA at small
   sizes. All text pairs measured >= 4.5:1 on their backgrounds (AA). */
