/* =====================================================================
   Mortis Cloud — the public site. One sheet for every page.

   Identity: "Assemblage" (docs/design-system.md). Graphite neutrals with a
   trace of warmth, one red (the ribbon), Schibsted Grotesk for headings,
   Atkinson Hyperlegible Next for text. A 4 px grid, three radii, one shadow.

   Theme: follows prefers-color-scheme; <html data-theme="light|dark"> set by
   the toggle (remembered in localStorage) overrides it. The dark values are
   written twice — once under the media query, once under the attribute —
   because CSS has no way to share a block between the two.
