/*
 * Interactive Checklists — Tier 1 styles
 *
 * Companion to docs/assets/javascripts/checklists.js.
 * See ARCHITECTURE.md for the feature design.
 *
 * Scope:
 *   - Enlarges task-list checkbox hit targets (mobile WCAG ≥ 44×44 px)
 *   - Styles the injected progress bar, reset button, and privacy note
 *   - Preserves checked state visibility in print view
