/**
 * Martin CC — Course Schedule Frontend Styles
 *
 * Brand alignment:
 *   - Flat editorial (no shadows, no card outlines)
 *   - Red accents (#cc0000) for sort arrows + delivery pills + focus rings
 *   - Light headline weights (400-500)
 *   - Body font baseline: 18px
 *   - Container queries over media queries (component-level responsive)
 *
 * Uses the existing brand `data-table` + `table-scroll` patterns as a base;
 * this file adds the schedule-specific toolbar, filter UI, sort affordances,
 * and expandable detail rows.
