   Scoped to #cavIhdManagementTopicContent. Designed-card pattern:
   tinted header band, a 🧠 "intuition" lead callout, flat labeled
   beats, tinted pearl footer. ONE card level, no nested boxes (the
   header / intuition / pearl are sibling tinted bands, not nesting).
   Single accent via --mi-accent; all reader text #111.
