/* hyperionos.ai v3 — the shared look of the new Home, lifted out of
   home-v3/home.css (33d4d78) for the inner pages (task #8413). Loads after
   ../site.css, so the type, colour, nav and footer are the site's own. One idea
   per screen, big pictures, few words. Every rule is scoped to body.v3, so a
   page that does not ask for it is untouched. home-v3/ keeps its own copy.

   A page is a run of beats, each a <section class="b ..." id="...">:
     .b-hero    one picture, one line, at most two buttons
     .b-words   words only, on a cold ground: a headline, its lines, one punch
     .b-warm    the same, on the warm ground the turn of a story sits on
     .b-cards   a headline over three things on the table
     .b-doors   pictures that open onto the other pages
     .b-cta     the close: one line, one price or name, one button
   A product picture keeps its own .show section; v3 only centres its head. */
