Second review follow-up.
Audit gate: a flat `npm audit --audit-level=<x>` cannot work here at any
level - the tree reports 102 advisories (12 low, 38 moderate, 52 high) and
`--omit=dev` does not change the counts, because gatsby itself is a runtime
dependency of the build. Gating on the tree as a whole stops publishing
permanently; ignoring it lets a new advisory through. scripts/audit-gate.mjs
fails on any critical/high advisory that is not in scripts/audit-baseline.json,
which carries an owner and a reason, so today's set is a tracked exception and
anything new blocks the deploy. Verified both ways: exit 0 on the committed
baseline, exit 1 with an entry removed.
Lint and typecheck: the deleted GitHub workflow was the only place they ran, so
`npm run typecheck` and `npm run lint` are now steps in the publish workflow,
ahead of the build. Lint could not simply be switched on - prettier reported 8
pre-existing files on main, all single-line indentation - so those are fixed
here and the check is clean rather than baselined.
Verified locally in the order the workflow runs: audit gate 0, typecheck clean,
lint clean (8 files reformatted, indentation only), build 136 pages.
