   Look: sober DACH-corporate academy aesthetic.
   Flat deep navy · one corporate blue · noble gold accent ·
   hairline rules · small-caps section labels · serif display
   headings · numbered role cards · generous whitespace.

   Scope: ONLY the frontpage (body.page-frontpage).
   Nothing here may affect chat / dashboard / admin pages.
