/* ============================================================
   Chiaro site chrome — the ONE header + footer for chiarohq.com.

   Every marketing page links this file and carries the markup from
   scripts/site_chrome.py. Do not copy these rules into a page's inline
   <style>: scripts/apply_site_chrome.py strips chrome rules out of the
   pages it stamps, so a local copy is both redundant and a drift source.

   Two nav variants:
     nav                  light, sticky  (default — every page)
     nav.nav--hero        dark, absolute (landing only, over the video hero)

   Layout relies on .wrap (max-width:1200px; padding:0 32px), which every
   page already defines identically. Colours fall back to literals so this
   sheet still renders correctly on a page with no :root block.
