/* TRShell — site styles.
   Ember, from the product's own DESIGN.md: graphite, warm text, ONE amber
   accent (it marks the active thing and the primary action, nothing else),
   green/yellow/red only for succeeded/warning/failed, 4px corners, flat
   surfaces, sentence case, system sans for prose and monospace for code.

   Systems: two breakpoints (768 / 1024), a 4px-based spacing scale, one type
   scale, one set of motion tokens. Components use tokens, never raw colours. */
