The router beforeEach guard was a 40-line inline function mixing auth
state checks, LAN bypass, and route resolution. Pulled the decision
logic into src/utils/authGuard.js — a pure function checkAuth(to,
authState) → {allowed, reason, redirect?} — that takes the auth store
as a plain object and returns a verdict. No Pinia, no vue-router, no
DOM imports. Trivially testable (21 spec covering LAN bypass,
already-authed-on-login, refresh-failed, etc.).

Router guard shrinks to 5 lines; AppLayout drops a redundant
router.push('/login') (auth.logout already navigates internally);
5 master-data views drop redundant onMounted initializeAuth() calls
(initializeAuth now runs once in main.js at boot).
