/* ============================================================
   Kuberiss — shared site chrome.
   Everything used by more than one page lives here: design tokens,
   resets, the type helpers, the sticky header (incl. the CSS-only
   mobile menu) and the footer. Page-specific layout stays with its
   page — the landing keeps its own <style> block, the legal
   documents load legal.css after this file.

   Mobile-first: base rules describe the phone, min-width queries
   widen it. Nothing here relies on hover or on JavaScript.

   Loaded AFTER _ds/.../styles.css, which supplies the fonts and the
   design-system custom properties this file references.
