/**
 * The unified dirty-state contract for modals: a promise-based house confirm
 * (`useConfirm`), a close guard that asks before discarding unsaved edits
 * (`useGuardedClose`), and the standing "Unsaved changes" footer chip

 * reimplementing the affordance — closing a dirty form must never silently
 * discard the edits, and the chip is the standing signal that edits exist.

/**
 * State-driven confirm dialog using `ModalV2` — the house replacement for
 * `window.confirm`. `ask(title, body)` returns a `Promise<boolean>`; the
 * consumer awaits the user's choice and then proceeds. The returned `dialog`
 * element MUST be rendered in the host's JSX (inside the host modal is fine —
 * `ModalV2` stacks).
 *
 * Concurrency: a second `ask` while a dialog is already open resolves `false`
 * immediately — without the guard the second `setPending` would overwrite the
 * first entry and the first Promise would hang forever. The ref-based
 * in-flight flag also covers two synchronous `ask()` calls in the same render
 * tick, which `useState` alone races.
