/* eqt-theme.css — v17 single source of truth
 *
 * Rules of the road (from the v17 brief):
 *   1. Token values are FINAL. No substitutions from per-page sprawl even
 *      where a local variant looks marginally nicer. One source of truth.
 *   2. Display font: Source Serif 4 site-wide. Body font: Inter.
 *   3. Per-page :root blocks MUST be removed. All pages import this file
 *      via <link rel="stylesheet" href="./eqt-theme.css"> before their
 *      page-local <style>.
 *
 * Chart-data colours (series, per-bin heatmaps, etc.) remain the only
 * legitimate source of new hexes outside this file.
