$('#prefs').onclick referenced a prefsModal that was never defined, and an
uncaught ReferenceError stops the whole script -- taking the theme toggle,
the feed filter, the event stream and loadFeeds() down with it, so the app
rendered an empty shell.
The scheduling patch had anchored on a function the rewrite already
deleted; str.replace matched nothing and said nothing.
tests/page-smoke.js executes the page against a stub DOM so this class of
failure is visible, since every server-side check passed while the UI was
completely dead. Handler wiring now skips a bad reference instead of
throwing.
