+<!-- PROTOTYPE (throwaway) — Slide 07 "The clinical ontology": three variants, switchable
+     via ?variant=A|B|C + floating bar (← → keys too).
+     Question: how to present 11+5 categories so the slide is more readable, livelier,
+     and with ENGLISH more prominent than Italian (audience mostly foreign).
+     A = three columns of 5-6 pills (user's idea) · B = editorial bands, EN-first pills
+     · C = split: ontology left, "why the order matters" panel right. -->
