/* Symbol page (/symbol/<SYM>): the hero quote, the stats strip, the sticky
 * tab bar with its sliding ink, the period chips and the chart readout.
 *
 * Built from the shared tokens and the "motion and play" vocabulary in
 * qe.css (.pulse-card, .seg, .switch, kbd). Nothing here uses the
 * live/backfill/backtest hues: being listed, being a universe member and
 * being in the model's book are statuses, not evidence states, so they are
 * drawn from --accent, --neutral and --warn-*. Signed values take --pos/--neg.
 * Every transition is behind `.fx` (set by fx.js) and inert under
 * prefers-reduced-motion (the reset in qe.css); without script the page is
 * static and complete. */
