   Public pages — About and Docs.

   Loaded alongside app.css, which still owns every token, font-face and base
   component (buttons, cards, tables, badges). Nothing here redeclares a
   colour or a font; it only adds the layout these two pages need that the
   authenticated app never did: a public header, a hero, a docs sidebar, and
   the comparison table.
