Supabase. Goals, study logs and posts live in Supabase tables, and sign-in runs through Supabase functions.
WebGL. The aurora behind the page is a small fragment shader. If WebGL is unavailable, a CSS gradient takes over.
localStorage. Your theme, device mode and session are remembered in the browser.
Theme and device mode are saved in your browser.
