Gatsby audit: static HTML that still ships no-store and a fat runtime
· Configuration notes, not a newsroom.
SiteRune fingerprints ___gatsby. SSG should be the easy mode for TTFB. It often is not, because the host sends no-store or the page hydrates a SPA anyway.
Static is a build, not a Cache-Control
If the HTML is prebuilt and the CDN still says private, no-store, perf-cache fires. Fix the host headers. Do not rebuild Gatsby to solve a CDN misconfig.
The runtime is optional. Act like it.
Gatsby sites fail AEO when the visible content is client-only. Prefetch every internal link if you want; still put titles, schema, and llms.txt in the static HTML. Headers at the CDN. We are not going to recommend a new Gatsby plugin for HSTS.
