   Shared by /about/ and /it/about/ — kept in its own file rather
   than inline (as /partners/ does) precisely because there are two
   language variants: inline would mean every tweak has to be made
   twice and the two would drift.

   Prefixes: .au-* page sections, .sa-* the smart-asset composition
   ported from the pitch deck (brief/smart-asset/). Generic class
   names are deliberately avoided — these pages also load
   Bootstrap 5, style.css and v2.css.
