/* Uluhanlı Yapı İnşaat — site styles. Built on tokens.css (design system v2).
   Rules followed throughout: square corners (inputs and chips 2px), no shadows, no gradients,
   structure with hairlines and the 32 x 4 gold accent bar, gold only as an accent,
   Archivo for headings and figures, DM Sans for text. Motion: 150 ms fades for interface states;
   content below the fold rises into view once as the page scrolls (see "scroll reveal"), and pages
   fade into each other (see "page transitions"). */

   Between pages the header stays put, the gold bar under the menu slides to the new page's item and the
   new page fades in over the old one with a 12px rise (the scroll reveal's motion). Chrome, Edge and
   Safari 18.2+; other browsers simply load the page. Screen only, never with reduced motion. */
