// ── The app is BUILT, not assembled once ──
//
// It used to be a module-level `new Hono()` with forty statements run at import. That cannot express
// installing a plugin: Hono's default SmartRouter throws `Can not add a route since the matcher is
// already built` the moment a route is added after serving begins, and Hono has no API to REMOVE a route
// at all — so uninstall was impossible even with a router that allowed adding.
//
// So nothing is added to a live app. A fresh one is built from the current plugin set and swapped in:
//
//     honoServer = buildHonoApp(plugins)      // install, uninstall, enable, disable — all the same call
//
// `server.tsx` serves it through a CLOSURE (`(req, server) => honoServer.fetch(req, server)`), not the
// bound `honoServer.fetch`, so the reassignment above IS the swap. Verified end to end: a route 404s
// before install, 200s after, and 404s again after uninstall, with core routes untouched throughout.
//
// Two things this buys over adding routes to a live app: the default SmartRouter is kept, so the fast
// RegExpRouter path survives — and uninstall is expressible, which an add-only API cannot do.

// Origin checking was removed on 2026-08-13, so CORS echoes back whatever Origin it is given. That is
// not a loosening: the check it replaced defaulted to off, so this is what every real install already
// did. The perimeter is the tailnet and the lock is a valid token on every protected route, plus the
// permission gate below.

// as a preflight — 204, no body, no DAV headers — and never calls the route beneath it.
//
// OPTIONS is not a preflight to a DAV client. It is how the client asks what the server can do, and the
// answer it needs is the `DAV: 1, 2, 3, calendar-access, addressbook` header. iOS sends it during account
// setup and refuses the account when it is missing, reporting the failure as "Cannot connect using SSL" —
// a message about TLS for a problem that has nothing to do with TLS, which is how this cost an evening.

// list. A hand-copied second list would drift, and the drift would be invisible until someone tried a
// prefix nobody had gated — which is precisely how the websocket hole happened.
//
// Order is irrelevant here: every prefix is distinct, so hono's registration-order matching has nothing to
