   KROTAR — /opina (public review form)
   Standalone page reached only via QR code. Mobile-first, fast to load:
   no WebGL, no external widgets — reuses the same color/spacing/type
   tokens and .glass-card / .btn / .eyebrow / :focus-visible system already
   defined in ../../style.css so the identity reads as part of the same
   site, just a lighter, single-purpose page.
