/* ═══════════════════════════════════════════════════════════════
   Matter Settle — Stylesheet (dual-theme)
   One file, token-driven, no preprocessor and no build step.
   Colours are defined once in the token blocks below and referenced
   everywhere via var(--token).

   ── HOW TO MODIFY ────────────────────────────────────────────────
   · ALL colors live in the token blocks below (:root = dark,
     [data-theme="light"] = light). To re-skin the whole site, edit
     tokens only — components reference var(--token) everywhere.
   · Layout sections are numbered; jump via the banner comments.
   · Add a new card? Reuse .feat-card / .uc-card / .content-card
     patterns already defined below rather than inventing new CSS.
