/* CONNEXUS 2026 photo gallery (gallery.html, en/gallery.html).
   Layout, type and colours follow the photographer's own gallery
   (visionimpress.gallery.photo) 1:1; the site nav/footer sit around it.
   Measurements taken from that page:
   - page #F9F8F6, headings #30363B, photo placeholder #E7E5E0, bar border #DBD9D4
   - titles Jost 300 (cover 80px / 47px phone, scenes 44px / 24px phone)
   - grid: 30px side padding (8px under 1024px), 2px inset per tile = 4px gaps
   - 4 photos per row from 1440px, 3 from 1024px, justified rows below that
   - lightbox on the page colour, image 58px from top/bottom */
