/* Smooth scrolling is an enhancement for anchor clicks the visitor makes, and
   it must NOT be active while the page is loading.
   With `scroll-behavior: smooth` on the root, the browser's own jump to a
   #fragment on load is an animation — and Chrome abandons it, back to the
   top, the moment the document's height changes under it. With a hero image
   and two webfonts still landing on pages this long, it was abandoned every
   time: arriving at /motoroptimering/#forfragan from the header CTA, the
   mobile-menu CTA or the action bar left the visitor at the top of a ~9600px
   page, with the form 6800px below them and nothing telling them so. The same
   applied to /kontakt/#forfragan.
   `html.ready` is added by main.js once the page has loaded, so the load-time
   jump is instant and reliable and every later anchor click still glides. */

   Two changes make the transition read as designed rather than abrupt:

   1. The ground is the warm off-white --paper-raised, not pure #FFFFFF.

      clinical; it also left white cards invisible against a white section.
   2. Where dark actually meets light, the seam is marked with the one red —
      the same small graphic detail used for section eyebrows. It appears
      only on the FIRST light section of a run, so two adjacent light
      sections do not draw the line twice. */
