/* About page — ported from the supplied about.html, styles kept as-is.
   Every selector is scoped under .about to avoid colliding with shared site
   classes that happen to share a name here (.impact, .hero, .eyebrow, footer),
   and the page's own design tokens (incl. a --red that differs from the
   site's) are scoped to .about instead of :root so they don't leak sitewide.
   The page's own <nav> markup/styles are dropped — this page uses the
