/* Shared chrome for saga-app.no — tokens, fonts, nav, buttons, footer.
   index.html and changelog.html each carried a hand-written copy of all of
   this, and the copies had already drifted (one kept a backdrop-filter the
   other removed for scroll performance; one kept a pre-WCAG --sub2). One
   file so they can't drift again. Page-specific styles stay in each page. */
