/*
  render-the-playground.css — "The Playground" (SKIN-G07) Render layer
  token map aligned to BU-CORE-UIUX-001 §4.1, 2026-07-03
  ===========================================================================
  Fires when data-theme="the-playground". ARENA/GAMIFIED category (student-
  facing only per BUP-UI-THEME-001 Rule 2).

  SOURCING CLASS: [AUTHORED PROPOSAL -- pending owner approval; no source
  values existed]. BUP-UI-SKIN-002 SKIN-G07 (lines 86-91) describes this
  skin only in prose: "Bright, cheerful, welcoming... yellows, oranges,
  bright greens... light, happy, energetic, safe, approachable... the
  antithesis of Fight Night." No hex values exist. This file authors a
  warm-orange accent on a soft cream canvas -- deliberately the lightest,
  warmest skin in the suite per the catalog's explicit design principle
  ("NOT the dark arena aesthetic").

  Contrast check (WCAG AA, BUP-UI-SKIN-001 L-9): text-primary #2b2013 on
  canvas #fff8ec = ~14.6:1. text-secondary #6b5638 on canvas = ~6.5:1 --
  passes 4.5:1 minimum.

/* ===========================================================================
   CONSTRUCTION FAMILY 8 of 8 — SOFT PAPER  [#234 / R-0823-01 / R-0823-02]
   Reference: NONE from the owner's kits -- the six terminals and SENTRY cards are
   all dark, glow-based worlds, and this family is the LIGHT, kid-safe counterpart.
   It is authored from the catalog prose (BUP-UI-SKIN-002: bright, warm, vibrant)
   and is PROPOSED for owner review, not owner-sourced.
   Frame strategy: a printed-card object -- 2px ink outline, HARD offset shadow
   in the accent (no blur), a dashed inner stitch line, and a strip of "tape"
   across the top edge.
   Light source: none (print). Depth is the offset shadow. Palette discipline:
   warm paper + ink + one bright accent; dotted-paper page.
   Type: heavy rounded-feel headings in sentence case, friendly and large.
   Interaction: buttons press INTO their shadow (translate) -- motion
   personality distinct from the glow families.
   [PILLAR-1: Fogg motivation + peak-end -- playful physical metaphors lower
   perceived effort for the youngest users; ink-on-paper keeps contrast high.]
