Screen galleries on feature pages, captured from the demo world - #1283

🟢 Confidence 10/10 · safe to merge
The only lines added since the last review are two guard clauses in a dev-only seed script; I read the whole reset path around them.
_{quality 100/100 · no findings · tests not needed · risk low}

Seed-gallery landing work, re-reviewed at 7268b05: the only new code is the --reset guard rejecting libpq host/hostaddr/service overrides, and it holds. Safe to merge. The open maple-landing/telemetry errors are failures in the deployed landing telemetry bundle and this change does not address them.

• seed-demo --reset now rejects ?host=, ?hostaddr= and ?service= in MAPLE_PG_URL before truncating
