/* ------------------------------------------------------------------
 * Checklist page styling.
 *
 * Accordion + checklist items use shadcn data-slot selectors
 * (`accordion-item`, `accordion-trigger`, `accordion-content`,
 * `item`, `checkbox`) with `data-state` / `data-status` attributes.
 *
 * Legacy class names (`.checklist-accordion`, `.checklist-item`,
 * `.checklist-mark*`, `.checklist-progress-*`, `.confirm-*`) stay on
 * the rendered DOM because `assets/js/checklist.js` queries by them
 * and persists progress against them; they are included as compound
 * selector list members so both old and new markup render the same.
