What gets verified on every release

✓Maths gate. Fifteen clinical and rendering functions in app.html are diffed byte-for-byte against reference/SHC_v3_canonical.html. A drift of a single character blocks the release.
✓Scenario suite. Five engine-verified clinical cases (Bella, Midas, Duchess, Apollo, Copperfield) plus five demo-flow tests run in a headless browser against the actual built artefact.
✓Performance. The PWA shell is precached on first load so subsequent visits are offline-capable and instant.
✓Schema. All public pages carry typed JSON-LD (SoftwareApplication, FAQPage, HowTo, DefinedTermSet, AboutPage) for accurate AI-overview citation.
