/* emulator.st — Arcade OS skin for the PLAY page ("arcadeos" data-theme).
   Refinement pass (2026-10-27): unified monochrome chrome — every control
   is the same quiet glass pill; color enters only as the cyan accent
   (focus/active/volume) and the magenta selection (active slot). Emoji
   glyphs are grayscale-filtered so the bar reads as one system.
   The game canvas pixels are NEVER touched — glows sit on the stage box,
   not the bitmap. Everything is scoped under html:is([data-theme="arcadeos"],[data-theme="arcadeos3d"])
   so every other theme (and the default) renders exactly as before.
   Geometry changes are desktop-only (min-width: 900px) — the session-47
   compact mobile HUD and the landscape-compact rules are left intact. */
