/* Kolton Sandbox — shared chrome, one external cacheable file instead of the
   same tokens/nav/button/footer CSS being duplicated inline on every page
   (index.php and every error page were shipping byte-identical copies of
   this on every load, uncacheable, and free to drift apart over time).
   Page-specific rules (hero, cards, error-code display, etc.) stay inline
   in each page's own <style> block, right after this file loads, so a
   page can override a shared selector by source order alone (see .nav on
   the error pages, which need a solid background instead of the floating
   transparent-over-video treatment used on the homepage). */
