/*
  QOR OS — qorsync.dev (ADR-123, ADR-127)
  Ancient-futuristic: obsidian and gilt, carved Roman capitals over a living lens that bends the sky. One accent, the
  launcher's ember; gilt is the structural counter (engraving, rules, numerals) and the metal of QOR OS's mark. A single
  dark look, set explicitly, as the launcher is.

  The showcase register of Demiurge's one look (ADR-108): every colour, face, radius and easing below comes from
  tokens.css, generated from docs/design/tokens.json, which every surface shares. The names here are the page's own.
