   The anatomical specimen plate of the canon library, mounted
   as an exhibit in The Archive. Global (not scoped) because the
   detail panel + telemetry DOM is built by js/serbres-brain.js.
   Everything lives under .brain-page. Type: Fraunces + IBM Plex
   Mono — both already loaded for other brands.
