A missing brace in a home.html inline <script> caused an app-wide login
outage (the whole block failed to parse, so boot never ran). Nothing in the
deploy path checked HTML syntax. Add tools/check-syntax.js: parses (never
runs) every inline <script> in server/public/*.html with vm and exits non-zero
on any syntax error, reporting the file + line.
Wired in two places:
- Dockerfile RUN after COPY server/ ./ — a syntax error now FAILS the build,
so it can't deploy.
- redeploy.sh pre-flight — fast local feedback before triggering the remote
build.
Verified: passes on current pages (16 blocks / 9 files); fails with the exact
location when a brace is removed.
