/* api/static/css/data.css
 *
 * Data tab styles. Extracted from styles.css in #2239 — pure relocation,
 * no behaviour change.
 *
 * Selectors covered: `.data-surface`, `.data-error-banner`,
 * `.single-activity-banner`, `.filter-row`, `.sport-pill`, `.search-wrap`,
 * `.date-range`, `.date-label`, `.export-split`, `.export-dropdown`,
 * `.pagination-*`, `.table-card`, `.act-table`, `.activity-cards`,
 * `.activity-card-*`, `.tss-*`, `.if-*`, `.expand-chevron`, `.detail-row`,
 * `.detail-metrics-*`, `.dm-*`, `.detail-weather`, `.detail-derived-header`,
 * `.detail-cards-row`, `.detail-metrics-card`, `.detail-chart-card`,
 * `.detail-zones-card`, `.chart-legend*`, `.chart-container`, `.chart-svg`,
 * `.chart-y-label`, `.chart-loading`, `.zones-donut-*`, `.zones-legend-*`,
 * `.zones-divider`, `.lap-table-wrap`, `.lap-tbl`, `.lap-effort-tinted`,
 * `.lap-corrected`, `.lap-adj-badge`, `.lap-corrected-note`,
 * `.lap-distance-*`, `.effort-bar`, `.effort-cell`, `.detail-swim-meta`,
 * `.swim-meta-*`, `.detail-activity-actions`, `.detail-loading`,
 * `.detail-loading-label`, `.ember-dot--d*`, `.table-loading-cell`,
 * `.table-error-cell`, `.cell-center`, `.detail-empty`,
 * `.detail-copy-mobile`, `.row-copy-btn`, `.threshold-card*`,
 * `.threshold-label`, `.threshold-value*`, `.threshold-unit`,
 * `.threshold-date`, `.threshold-empty`, `.threshold-edit-*`,
 * `.threshold-history*`, `.threshold-step-chart`, `.threshold-btn-*`,
 * `.threshold-zones-grid`, `.threshold-popup*`,
 * `.threshold-suggestion-*`.
 *
 * Deferred from extraction (stay in styles.css):
 *   - `.sport-icon*` — shared with Profile season stats (see styles.css
 *     comment at the `.sport-icon` definition).
 *   - `.sport-badge*` — shared with Plan and Race surfaces.
 *   - `.view-on-strava-link*` — shared with Home and Plan surfaces.
 *   - `.zone-strip-item` — shared with Plan plan-week phase strips.
 *   - The grouped drawer + sheet shells (`.thresholds-overlay`,
 *     `.thresholds-drawer`, `.thresholds-sheet`, etc.) which share
 *     selectors with `.races-*` and `.pipeline-settings-*`.
 *
 * Modify in place. Bump api/static/sw.js CACHE_NAME on every change.
