/* ═══════════════════════════════════════════════════════════════════
   RESTORED — .form-input-wrap and the custom .checkbox__box variant
   ═══════════════════════════════════════════════════════════════════
   These were part of the original forms.css and are still referenced
   by several already-written files (student-list.js, family-management.js,
   sibling-linking.js, enroll-student.js, reminders.js, notifications.js).
   Added back here additively — nothing above this block was touched —
   so those files keep working without needing to be rewritten again.
   Uses the real accent tokens (--accent/--accent-glow), not the warm
   --role-primary palette, to stay consistent with the rest of the app.
