/* Off-white (light gray) header & footer surface, replacing the old green.
   Linked on every page EXCEPT noboa-torres and rogue-house, which keep
   their own case-study colors. Loads after each page's inline <style> and
   after site-type.css, so it wins at equal specificity. Fallback values
   keep it working on pages that don't define the shared design tokens. */
