/*
  render-the-garden-dark.css — "The Garden Dark" (SKIN-G09) Render layer
  token map aligned to BU-CORE-UIUX-001 §4.1, 2026-07-03
  ===========================================================================
  Fires when data-theme="the-garden-dark". ARENA/GAMIFIED category
  (student-facing only per BUP-UI-THEME-001 Rule 2). Phase 2 target.

  SOURCING CLASS: [AUTHORED PROPOSAL -- pending owner approval; no source
  values existed]. BUP-UI-SKIN-002 SKIN-G09 (lines 100-104) describes this
  skin only in prose: "deep purple or deep navy backgrounds with pink and
  lavender accents and glow effects... dramatic, elegant, glowing... the
  color is pinker/more violet rather than deep amethyst" -- an EXPLICIT,
  documented instruction to stay warm-pink-violet rather than ViralDecay's
  cool deep amethyst #8B5CF6 (catalog line 96, 103). The accent hue below is
  chosen warmer/pinker than #8B5CF6 specifically to honor that documented
  distinction, not to invent an arbitrary purple.

  Contrast check (WCAG AA, BUP-UI-SKIN-001 L-9): text-primary #f7ecf5 on
  canvas #150a1a = ~16.8:1. text-secondary #d1a8cc on canvas = ~9.8:1 --
  passes 4.5:1 minimum.

/* ===========================================================================
   CONSTRUCTION FAMILY 7 of 8 — SPATIAL GLASS  [#234 / R-0823-01 / R-0823-02]
   Reference: six-terminals.html 06 "Spatial Glass -- visionOS, real AR rules".
   Frame strategy: NO drawn frame. A heavily rounded slab of real frosted
   glass: translucent fill, strong backdrop blur + saturation, a 1px specular
   edge and a top inner highlight. Depth comes from the soft drop shadow and
   from the coloured light pools the glass sits in front of (body).
   Light source: the page behind the glass (four tinted pools); the glass
   itself does not glow.
   Palette discipline: soft multi-hue pools, white-ish glass, ink stays the
   skin's own main text colour.
   Type: system sans, semibold, tight tracking, sentence case (no caps voice).
   backdrop-filter is used here WITHOUT clip-path (#228): the roundness comes
   from border-radius only.
   [PILLAR-1: Fitts + Gestalt common region -- large rounded targets; the glass
   plane is the single grouping cue.]
