/* KI-Entwicklung (ai-development.php) - the page's own stylesheet, loaded after site.min.css via $pageCss.
   Ported from the approved prototype V3.1 round 10 (_scratch/ki-service/v3/r10-build, DECISIONS.md #ki-seite):
   the rules of the owner's pick per section, scoped under .ki so nothing reaches the site header or footer.
   Buttons are the site's CTA system B1 (cta.css), the FAQ is components/faqs.php.
   Colours: the brand tokens below (master: C:\Users\accou\Claude\vitec\branding\tokens\tokens.json) or alphas of
   them - no other hex. Classes on <html>: anim (entrances may start hidden), gl (the particle object may run),
   gl-ok (WebGL is running: steps wait for the particles), nogl (static final state), ki-page (this page). */
