+// Homepage. Ported from the legacy static apps/web/public/index.html so it
+// participates in the Astro build pipeline. Inline CSS and JS are preserved
+// verbatim under `is:global is:inline` and `is:inline` respectively; the
+// explorer JS still fetches live data from api.docxcorp.us at runtime, same
+// as before.
+//
+// This page intentionally doesn't use the shared Layout.astro because its
+// header/footer chrome and SEO metadata (custom og:title brand tagline,
+// twitter:description with "The missing dataset" copy, full Dataset JSON-LD
+// with variableMeasured/inLanguage/measurementTechnique) differ from the
+// shared one. The other Astro pages still go through Layout.
