   Bion · Seasonal World — private face (locked spec §5)
   --------------------------------------------------------------------------
   The semester is a season. The private chrome is the night-valley keep of
   that world: deep valley-night skies with stars, a wooden signpost banner
   (same wood as the public face's nav), parchment plaques with gold edges,
   and a golden-hour "arrival" for the login. Courses are lit places on the
   map; deadlines shift the environment (urgent amber, overdue crimson).

   Mirrors engines/bion/app/assets/stylesheets/bion/public.css so both faces
   speak one world: the same golds, the same parchment, the same night tones.

   Pure CSS/SVG decoration — no raster images, no external fonts (system
   serif stack). Variable names are stable — feature sheets (schedule,
   quizzes, ingestion) consume them and re-theme automatically.
   ========================================================================== */

     and the deadline red. */
