Cloud backup — not connected

To sync across devices, connect a free Supabase project (no credit card). Create a project, run SETUP.sql in its SQL Editor (makes the data table + private videos bucket), turn off “Confirm email”, then paste your Project URL and anon key into js/cloud.js. Full step-by-step is at the top of that file. Once connected, everything — including every video you upload — follows you to any device you sign in on.
