The job checks out into the runner's own workspace, not
/opt/ruvdstests where DEPLOY.md has the human create a .env file — so
docker compose here had no .env to read JWT_SECRET from and failed
outright. POSTGRES_PASSWORD would have silently fallen back to the
compose file's devpassword default instead of erroring, which on
Deploy would have broken auth against the already-initialized pgdata
volume.
Host-mode jobs execute directly on the bare runner container rather
than a per-job container, and actions/checkout is a JS action — it
needs `node` on PATH to run at all, which the runner image doesn't
ship. Failed every run with "Cannot find: node in PATH" before any
other step got a chance to install anything.
Replaces the single long scrollable list of every question with one
card at a time plus arrow navigation, so a student's focus stays on
the current question instead of the whole quiz at once.
Sources could already draw from any number of topics, but the picker
UI only ever showed one topic's questions at a time, forcing a teacher
to lose their place switching between topics while assembling a quiz.
