   CURERIS PANEL (/panel)
   A deliberately separate visual identity from the Cureris marketing
   site: paper + spruce, IBM Plex, clinical typography. An independent
   evaluation body that looked like its parent's sales pages would
   undercut the independence it is claiming. Scoped to panel.html only.
