/**
 * Checkbox component - native checkbox input element.
 *
 * @accessibility
 * - Uses native `<input type="checkbox">` (role="checkbox" is implicit)
 * - Must have accessible name via `<label>`, `aria-label`, or `aria-labelledby`
 * - Native `checked` property handles checked state
 * - Uses native `disabled` attribute for disabled state
 * - Use `aria-invalid="true"` when validation fails
 *
 * @example
 * ```tsx
 * // With label element
 * <Checkbox id="agree" />
 * <label htmlFor="agree">I agree</label>
 *
 * // With aria-label
 * <Checkbox aria-label="Subscribe to newsletter" />
 * ```
 *
 * @wcag 4.1.2 Name, Role, Value - checkbox must have accessible name
 * @wcag 1.3.1 Info and Relationships - label must be programmatically associated
