/* ============================================================
   site.css — shared site chrome for index.html and gallery.html.
   What belongs here: the pieces that must look identical on every
   page — the universal reset, :root design tokens, the fixed nav,
   the mobile menu, and the footer, plus their shared mobile rules
   and the reduced-motion accessibility fallback.
   What does NOT belong here: page-specific layout (hero, sections,
   gallery masonry, forms, project nav) — those stay inline in each
   page's own <style> block. Loaded before lightbox.css on both pages.
