// Lightweight two-click confirm for a destructive-but-recoverable button
// ("mark all read", "mark done") — deliberately NOT the old modal system
// (@hive/shared/modal.js's `themedConfirm`, itself built on the
// shadow-DOM `<hive-dialog>` custom element): a full backdrop+dialog is
// more machinery than a "did you mean to click that" nudge needs, and
// mara's ask for this rewrite was real Preact components, not a port of
// the old widget family. First click arms the button (caller renders a
// distinct "sure? click again" label off `armed`); a second click within
// `resetMs` fires `onConfirm`; anything else (timeout, blur) disarms.
