{# Reverted: common.js / url.js were added with SKIP_AUTH_REDIRECT to enable
a showToast on this page, but authService.js is self-contained and the
existing showAlert() already gives the user success feedback. Pulling
these out so common.js's auth-guard can't redirect /register/ → /login/
on production when SKIP_AUTH_REDIRECT isn't honored by an older common.js. #}
