/* chrome.css — shared site chrome (SOURCE FILE, hand-maintained)
   Tokens, reset, base typography, header/masthead/nav/hamburger/mobile-drawer,
   buttons (.btn-docket-header / .btn-subscribe-mobile), footer, .mono, common utilities.
   Consumed by every page on the site: build-live-surfaces.py's externalize_article_css()
   COPIES this file verbatim to build/assets/chrome.css (and mirrors to the SFTP folder) —
   it no longer harvests chrome CSS from the hub template's <style>. Edit HERE, not there.
   --color-text-faint already carries the WCAG AA lift (4.83:1); enrich_pages()'s faint-token
   replace on build/assets/chrome.css is now a harmless no-op against this source.
