/* Header colour-invert (contacts.html) — this page has no dark hero for the

   doesn't reliably blend a position:fixed element against scrolled content
   (verified: renders as plain white, invisible on a white page — a known
   fixed+blend limitation), so instead JS toggles .on-dark on #hdr depending
   on whether a dark block is currently under the header (see initHeaderInvert
   in main.js): frosted light bar + dark ink text on the light page, frosted
   dark bar + white text once a dark section (the .contact card) scrolls
   underneath. The accent logo dot and the filled "Оставить заявку" button are
   left out of the text-colour swap on purpose — both already read fine on
