/*
  PLAYRS-MUSEUM-V1 -- owned by js/playrs-museum-v1.js.
  The museum behind ARCHER's frame. The hall is three.js; this file styles the chrome over it:
  top line, the work panel (bottom sheet on phones, right column on desktop), the index below.
  Theme tokens plus the site red; accents are red and black (Nate, 2026-10-25). The hall follows the
  theme in JS (white cube in light, dark gallery in dark).
