   KATER'INA — portfolio
   Source: Figma frames 1:2 (desktop 1920x1080) and 1:52 (mobile 375x991).

   Desktop scales proportionally: --u equals 1px at the 1920 reference width
   and shrinks/grows with the viewport, so every dimension keeps the exact
   Figma proportions at any desktop size. Tablet/phone reset --u to 1px and
   restructure the layout.
