/* ============================================================
   Humanoid.Company — corporate site
   Design system: "Dossier" (adopted from variants/dossier)

   Philosophy, shared with HumanoidOnline so the group and its
   flagship read as one continuous thing:
     - warm paper ground / near-black ink
     - zero radius: rules and hairlines, never shadows
     - monospace carries every label, enum and datum
     - serif display headlines in sentence case
     - numbered sections on a left numeral rail
     - status as typed enum tokens; UNKNOWN is a real value

   THEMING
   Every colour is a semantic token. The raw palette is declared once
   and each theme remaps the same token names, so no component rule
   ever names a literal colour.

     no data-theme          -> follows the OS
     data-theme=light|dark  -> explicit choice, see js/theme.js

   The dark block is guarded with :not([data-theme="light"]) so an
   explicit light choice still wins on a dark-set OS; the
   [data-theme="dark"] block repeats it so the toggle wins both ways.

   CONSTRAINTS
   - No webfonts: font-src 'self'. These are the fallback stacks
     HumanoidOnline itself declares.
   - No inline styles anywhere: style-src 'self'.
   - Dark ink on the accent, never light. Paper on this orange
     measures 2.83:1 and fails AA. See variants/README.md.

     Deliberate brand decision: the site presents dark regardless of the
