/*
  render-the-academy.css — "The Academy" (SKIN-G02) Render layer
  token map aligned to BU-CORE-UIUX-001 §4.1, 2026-07-03
  ===========================================================================
  Fires when data-theme="the-academy". ARENA/GAMIFIED category (student-
  facing only per BUP-UI-THEME-001 Rule 2) -- catalog lists it under Arena
  skins (BUP-UI-SKIN-002 summary table) despite the light/executive-adjacent
  feel of its prose description.

  SOURCING CLASS: [AUTHORED PROPOSAL -- pending owner approval; no source
  values existed]. BUP-UI-SKIN-002 SKIN-G02 (lines 55-59) describes this
  skin only in prose: "Clean lines. White or near-white base with royal
  blue or cobalt accents... premium city studio, boutique, professional,
  aspirational... light, crisp, modern." No hex values exist anywhere. This
  file is authored as a LIGHT canvas variant using the same royal-blue/
  cobalt accent family the catalog names, distinguished from Cobalt Light by
  warmer near-white canvas and softer, more rounded glass treatment (per the
  "boutique studio" character description vs. Cobalt Light's "executive"
  register).

  Contrast check (WCAG AA, BUP-UI-SKIN-001 L-9): text-primary #14213d on
  canvas #fbfbfd = ~15.8:1. text-secondary #48566e on canvas = ~7.2:1 —
  passes 4.5:1 minimum.

   Reference: six-terminals.html 01 "System Window -- anime minimalist".
   Frame strategy: ONE hairline frame, a ruled header strip under a centred
   small-caps title, and a short title notch on the top edge; nothing else.
   Light source: none to speak of -- a faint soft halo only (restraint).
   Palette discipline: the skin's own ink + one accent; flat surfaces.
   Type: light weight, centred headings, system voice (~0.34em tracking, small
   uppercase) reserved for the header strip label.
