/**
 * Immediate binary state toggle (On/Off).
 *
 * @description
 * Differs from `<Checkbox>` in that it implies an immediate setting change
 * without requiring form submission (e.g., enabling/disabling a feature).
 * Supports the standard size scale (`sm`, `md`, `lg`).
 *
 * @ai-rules
 * 1. Always pair with a sibling `<Label>` component linked via `id` and `htmlFor`.
 * 2. Use `checked`/`onCheckedChange` (not `value`/`onChange`) to control state.
 * 3. Use the `size` prop to match surrounding form element sizing.
