Subject: [PATCH] quality: fix heading order + asset caching (0.84.0)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

measured the LIVE site with Lighthouse (best-practices 100, seo 100,
agentic-browsing 100; a11y 98, perf 86) and fixed two real flags:
- heading-order: the footer column labels were <h5> following an <h3>
  (skipping h4) — changed to <h4> so the page heading order is sequential;
  a11y 98 -> 100
- caching: every static asset was served with no cache lifetime (0s).
  added nginx cache locations on the amerc.ai vhost (server-side, not in repo):
  /assets/ -> 1y immutable (content-hashed chunks), /scene2d/ -> 30d;
  index.html stays uncached so it always points at the latest assets.
  repeat visitors now serve JS/CSS/images from cache. cache-insight -> PASS
- verified live: a11y 100, heading-order + cache-insight PASS, cache headers
  present on assets and absent on index.html
