/* =============================================================================
   RAYASA — Startups & MVP landing page (/services/startups)
   Loaded by services/startups.html only. Every class here starts with `su-`;
   the shared components (buttons, badges, fields, choices, FAQ, ab-head,
   sv-hero) are reused as they are and only adjusted from inside a `su-`
   context, so nothing elsewhere on the site can change because of this file.

   The page spends its boldness on one picture — the product growing stage by
   stage, with what each stage costs beneath it — and keeps everything else in
   the site's quiet register: hairlines instead of boxes, one accent per role.
