/* Training (ADR-0185, ADR-0186, ADR-0187)
 * Scoped to #tab-staff-training. Uses the app's design tokens for typography,
 * spacing, colour, radius and shadow so the page reads as native to the rest of
 * the product. Families:
 *   tr-*        the page: frame, band, lists, rows, cards, forms, editors
 *   training-*  the lesson reader (rail, card chrome, long-reading sections, question cards)
 * Owners elsewhere, USED here and not redeclared: .attendance-toolbar, .state-chip,
 * .empty-state, .row-actions, .info-bar, .settings-callout, .settings-attention,
 * .settings-subnav, .titled-section, .chip, .class-checkin-banner, .form-*.
 * No one-sided accent borders, no gradients, no pills (radius-sm on every badge).
