/*
 * NEXT Symposium — Indico conference stylesheet
 *
 * Palette rationale:
 *   Header: deep institutional navy (#14304f) — reads sober / trust
 *   Subtitle & announcements: warm cream (#f4f0e6) with navy text — softens
 *      the clinical feel typical of conference software
 *   Accent (selected menu item, hover underlines): warm gold (#b8892b)
 *   Menu: soft cool-gray, thin borders — quiet, doesn't fight for attention
 *
 * The Indico standard.css exposes these `--conf-theme-*` variables. Anything
 * beyond that lives in the freeform block at the bottom.
