/* =============================================
   SITE CHROME — navbar + footer styles
   Markup and behaviour live in site-chrome.js.
   Relies on the page's design tokens (--nav-h, --border, --brand, …)
   and, for <site-footer cta>, its .wrap, .rev, .hu, .btn-primary and
   .sol-corner styles.

   Layout follows the page's fixed content frame when the page defines one:
     --frame        content frame width per tier (1200 / 960 / 680px, 100% on phones)
     --fw           width that frame-scaled type is based on
     --footer-side  side padding of the footer CTA block
     --footer-card  footer card width on tablet
   Every value falls back to the older viewport-based layout, so a page
   without these variables renders exactly as before.
