// checkAdmin reports whether the session belongs to an account with the

// login or account republish, so it is NOT trusted as the source of truth:
// removing admin: true from an account file (or the admin API's reload) must
// demote an already-connected admin without requiring a relog. The account
// file is re-read on the owner goroutine, which serializes with logins and
// account saves, so the check cannot race a concurrent hash/admin change.
// Privilege checks fail closed when the account cannot be read.
