/* ============================================================
   fengshui-room.css — the Commanding Position interactive.
   Dark-glow design language (doc 09). The whole tool reads as a
   level-3 "raised" surface: a base gradient, a persistent quiet
   bloom, a moonlit top rim, hairline dividers, editorial spacing.

   Tokens rule everything for color / space / motion. The room and
   the bed use tasteful LITERAL wood / linen / glass tones so the
   plan reads like a warm architectural drawing at dusk, while the
   GLOW and every active state stay on --accent (jade on this page,
   which is scoped .section--fengshui) so the luxury layer re-tints
   with the section. Motion is opacity + transform only; no blur is
   animated; every animation is guarded by prefers-reduced-motion.

   NOTE ON LOCAL TOKENS: doc 09 §1's glow tokens (--surf-2,
   --moonlight, --halo, --hairline-accent) are not declared globally
   in tokens.css, so — exactly as animal-sections.css does — we
   declare self-contained helper tokens scoped to .fsr-tool, derived
   from the real tokens. No global token is renamed or redefined.

   All selectors are prefixed .fsr- so they never collide with the
   .pf-* shell.
