 * Checkbox — built on Radix Checkbox.
 *
 * Supports tri-state via `checked="indeterminate"`. Violet fill when on,
 * border-only when off. Themed via tokens (--primary, --background).
 *
 * The `size` prop accepts `"sm" | "md" | "lg"`. Default `md` preserves the
 * 16px box from before this prop existed. The `sm` size keeps a >=24px
 * effective tap target via an invisible expanded hit area (WCAG 2.5.5).
