+TODO: Extract checkbox pattern into reusable Checkbox component
+- Create src/components/input/Checkbox.vue with:
+  - Hidden native <input type="checkbox"> for accessibility
+  - Custom visual styling matching this implementation
+  - Semantic tokens (--primary-background, --input-surface, etc.)
+- Use this Checkbox component in:

+  - MultiSelect.vue option template
+  - SingleSelect.vue if needed
+- Benefits: Consistent checkbox UI, better maintainability, reusable design system component
