/* ============================================================================
   ROOM 101 · BETTY ADVISORY CONSOLE
   A light pastel instrument panel docked in the right margin of the Purple
   Room. It reads as installed equipment against the deep violet dark, not as a
   chat widget dropped on the page.

   Rules this file obeys:
     · pastel surface, dark ink, one violet accent. no loud neon.
     · no bubbles, no avatars, no stacked transcript.
     · the lesson outranks the console; the console outranks the trail.
     · the trail is faint memory, not active chat.
   It only adds .betty-* rules, two .rail additions, and margin reservations on
   the existing fixed furniture, so nothing in the room can be restyled by
   accident.
