   chrome.css — nav + footer.
   Modelled directly on attio.com's top bar: white, 64px, a hairline underline
   that is present AT REST (ref/attio-hero.png is a scroll-0 capture and the
   rule is visible there — an earlier note in this file claimed otherwise and
   was wrong), wordmark left, plain text links, ghost + dark button pair right.
   Scrolling changes only the background to a blur, never the rule.
