// One confirm surface for the whole Settings view.
//
// WHY IT LIVES AT THE VIEW ROOT AND NOT IN THE PANELS: every section is a
// Column inside SettingsView's Flickable, so a modal mounted in a panel is
// sized by the scrolled content and clipped by the viewport — it would ride
// the scroll instead of covering the window. This mounts once, last, at the
// view root (over the sub-nav too) and the panels are handed a reference to
// it beside their `doc`.
//
// The reference raises NATIVE rfd message boxes for these
// (local_library_settings.rs:607-626, plex_auth.rs:963/997). This port has an
// in-app confirm surface already — controls/QbzConfirmModal.qml — so the
// prompts stay inside the window, but the STRINGS and the STEP COUNT are 1:1
// with the reference: the danger-zone clear asks twice, Plex asks once.
//
// Two separate modal instances rather than one reused instance: chaining
// would mean rewriting `title`/`body` from inside the first modal's own
// `confirmed` handler, and the two prompts also want independent focus
// lifetimes (QbzConfirmModal grabs focus on open and restores the shell root
// on close). Cheap enough — they are inert Items while closed.
