/* =============================================================================
 * TICKER SPARKLINE MODAL — shared between easycompare and discover
 * =============================================================================
 *
 * Multi-period sparkline grid for a single ticker. The JS lives at
 * `js/sparkline/tickerSparklineModal.js` (also shared).
 *
 * Why standalone:
 *   - Originally lived in css/betterthanspy.css alongside the discover-app
 *     styles. When easycompare started using the same modal we had two
 *     options: (a) load all of betterthanspy.css from index.html (drags in
 *     hundreds of unrelated discover styles, plus name-collision risk on
 *     shared classes like .sparkline-cell), or (b) extract just the modal-
 *     specific block into its own file. We picked (b).
 *   - Both `discover.html` and `index.html` now load this file directly.
 *     `betterthanspy.css` no longer contains the modal block — see the
 *     "TICKER SPARKLINE MODAL" section there for the (now removed) origin.
 *   - The cell-sparkline styles (`.sparkline-cell` rules in
 *     `#discover-table` / `#ranking-table`) STAY in their respective app
 *     stylesheets because they're table-scoped, not modal-scoped.
 *
 * Theming:
 *   - All colors source from CSS custom properties (`--bg-primary`,
 *     `--success`, etc.) defined globally — light/dark mode "just works"
 *     without any media queries here.
 *   - Animation `compare-spin` is keyframe-defined at the bottom so this
 *     file is fully self-contained (originally lived in betterthanspy.css
 *     and was implicitly inherited).
