Is this just a static HTML demo?

No. Frontend is static on GitHub Pages, but auth + data go to a real backend (PHP 8.3 + SQLite) running on my PC for now. Guard checks token via /api/me on every open. Full entrypoint in EXP 011.

Why no framework? Is vanilla production-ready?

For this scale yes. Four small files (guard/store/app/auth) are easier to review and faster to iterate than framework boilerplate. No build step means GitHub Pages deploy is trivial.

Why does login sometimes fail?

Backend is not on a 24/7 VPS yet. It lives on my personal PC, online daily 08.00–21.00 WIB (UTC+7) when my PC is on. Outside those hours API is unreachable and login cannot succeed. Frontend shows a toast and stays readable. Screenshots remain as proof.
