Root cause of re-login failing after first-run setup: on EasyPanel/w/o a volume, the
container's /app/backend/data (users, incl. the changed admin password) is wiped on every
recreate, so logging back in with the new password fails. Added:
- ENV DATA_DIR=/app/backend/data (explicit) + VOLUME declaration in Dockerfile
- README 'Data persistence' section: must mount a persistent volume to /app/backend/data
Verified: backend + live server login>setup>relogin-with-new-password works (200); the
failure is deployment data persistence, not login logic.
The Vue SPA is now built locally and its frontend/dist/ committed (force-added).
Dockerfile is a single-stage runtime: copy prebuilt dist + python:3.11 + Flask.
No node/npm inside the image -> deterministic, no npm/esbuild postinstall flakiness.
To update UI: edit src, npm run build, commit frontend/dist/.
