// Global app settings (key/value, cached). Primarily used for the tenancy mode.
//
//   tenancy = 'solo'   -> exactly one site (the primary/owner site)
//   tenancy = 'circle' -> solo site that federates with other solo Klonkt sites
//
// HUB MODE IS REMOVED (2026-06-24): multi-artist-per-domain was dropped in favour
// of solo + Cirkels. getTenancy() coerces any legacy 'hub' value to 'solo' so all
// the old `tenancy === 'hub'` branches are unreachable; the hub code is being
// deleted incrementally.
//
// The cache is updated immediately on setSetting, so a toggle in admin
// takes effect live without a restart.
