/* ── Bottom sheet (mobile-driven interaction) ─────────────────────────
 *
 * Promoted from matos's local CSS by the 2026-06-01 audit (§3.4). The
 * class names still carry the historical `matos-bs-` prefix; a future
 * naming sweep will rename to `bs-*` once campscout and secretariat
 * adopt the pattern. For now the rules live here so consumers can
 * `<link rel="stylesheet" href="/vendor/style/bottom-sheet.css">`
 * instead of duplicating the block.
 *
 * Anatomy:
 *   .matos-bottom-sheet-backdrop  fixed full-screen scrim
 *   .matos-bottom-sheet            sliding panel anchored to bottom
 *   .matos-bs-handle               drag affordance (top center)
 *   .matos-bs-header               title row
 *   .matos-bs-header h2
 *   .matos-bs-close                close button
 *   .matos-bs-toolbar              optional action row above the list
 *   .matos-bs-list                 scrollable list container
 *   .matos-bs-row                  one selectable row
 *   .matos-bs-group-header         section header inside the list
 *   .matos-bs-footer               sticky footer area
