/* ─────────────────────────────────────────────────────────────────────────
   Romain Mélisen — CV

   The rule that governs this sheet: the accent hue is spent on data and state
   only — level marks, scroll position, focus, the active section. It is never
   spent on a heading, a border, or a mood. Everything structural is a hairline
   in a cool grey that does none of the speaking.

   Two mediums: dark (default) and light. Both are checked for AA contrast —
   see the ratios noted beside the tokens.
