/* ═══ CREWHUB · HORIZON — Design System ═══ */
/* Faithful to the Horizon maquette: warm paper base (#f3f2f2), teal accent
   (#168C9B), Libertinus Sans throughout (headings at 600), JetBrains Mono for
   codes/figures, crisp low-radius surfaces (flat cards, border only — no drop
   shadows). :root carries the light palette; dark is an opt-in via the topbar
   toggle. Class names are unchanged so every module inherits the retheme. */
