/* qe web — the visual system.
 *
 * One idea: this is an audit instrument, not a product dashboard. Cool paper
 * surfaces, a single accent, and three *evidence states* — live, backfill,
 * backtest — as reserved colours that nothing else may borrow. Every number
 * sits in a real monospace with tabular figures; headings are set in a serif
 * so the pages read as a written record. Both themes are designed from the
 * same token set (the categorical hues were validated for CVD separation and
 * contrast in each), and every component takes its colours from the tokens,
 * never from a literal. Fonts are vendored: nothing loads from a CDN.
 *
 * Every panel is built in three layers so a reader can stop at any depth:
 *   1. `.panel-head`  — a title and one plain sentence saying what it shows;
 *   2. tiles / charts — the numbers, each with its SE and n where defined;
 *   3. `details.explain` — the method and the caveats, closed by default.
 * Amber (`.caveat`, `.alert`) is reserved for things the reader must not
 * miss; routine methodology notes use the quiet `.note`. */
