   DARK MODE — toggled via the topbar switch (saved to
   localStorage; honours prefers-color-scheme on first visit).
   Mostly re-defines the tokens; a few controls hard-code
   ink/white and get explicit overrides. Grounded in dark
   analytics references (Mocha, Runey): very dark canvas,
   slightly-raised card surfaces, one bright accent, hairline
   borders for elevation.
