/* The workstation environment — the depth layer's own material system.
   Companion to web/shell.css (the permanent Table shell): shell.css defines
   the --hz-* material tokens on :root; this file carries them INTO the
   depth layer so a workstation is a working plane inside the same dark
   institutional environment, never a white application inside a dark frame.

   Two mechanisms, deliberately separated:
   1. RETOKENING — the legacy stylesheet and nearly every legacy inline
      style read the CSS custom properties --bg/--fg/--muted/--line/
      --accent/--accent-bg/--focus (plus --danger/--warn added at :root by
      this change). Redefining those properties on #workstation-layer
      re-resolves every var() beneath it: one scope, ~74 workstations.
   2. RECOMPOSITION — structural rules below that reshape the working
      plane, rail, forms, tables, records, and states as materials
      (smoked glass, engraved labels, restrained borders), not merely
      recolored rectangles.

   Palette discipline: every color derives from the seven real HVI brand
   values already committed in web/landing.html — Caviar (#302E2F family
   grounds), Secret Garden (#4F563C glass tint), Garden Gate (#8B9165
   live accents), Antiquarian Brown (#946C46 gold detail), Neutral Ground
   (#E3DACC text), Sommelier (#664747 consequence red), khaki (#BAAE96
   secondary text). No invented hues; dark variants are these values
   darkened, never replaced. */
