/* =====================================================
   YUGANTIX — Theme v4 PREVIEW (about.html)
   Mirrors the same system applied to index.html:
     - light mint page background, lightened twice per feedback
     - solid white header (no translucent cream blur)
     - "deep" alternating sections -> white
     - first section (hero) and last section (final CTA wrapper) -> white
   Plus: proper FAQ accordion styling, since .faq-item/.faq-question/
   .faq-answer had no CSS at all before this — it was rendering as
   plain unstyled buttons and always-visible text.
