/* ============================================================================
   SMART SUITE — COMPONENT LIBRARY
   ----------------------------------------------------------------------------
   This is the full kit. A new page should be assembled almost entirely from
   these classes. Before writing any new CSS for a page, check here first —
   if you need something genuinely new, add it to THIS file (with a comment
   block in the same format) so the next page can reuse it.

   Every component is surface-aware: it reads --surface / --border /
   --text-strong / --text-body / --accent, which are set by .on-dark, .on-light
   or .on-wash on the parent section. Do not hard-code colours in components.

   01 HEADER & NAVIGATION
   Mobile-first: hamburger opens a full-height panel. Desktop (>=980px) becomes
   a horizontal bar. The header is transparent over dark heroes and turns solid
   on scroll (theme.js toggles .is-stuck).

   USAGE: copy the <header class="site-head"> block verbatim from
   templates/page-template.html onto every new page and set aria-current="page"
   on the active link.
