/* ============================================================
   Airpiv — Shared layout styles for static content pages
   (about.html, contact.html, privacy.html, terms.html, 404.html)
   Colors/fonts extracted directly from index.html's :root and
   header/footer rules. The shared color/radius tokens (kept in sync with
   css-tokens.css) are inlined here rather than @import-ed: a CSS @import is
   a render-blocking, serial round-trip (the browser must fetch this file,
   parse it, THEN fetch css-tokens.css), which delayed first paint. Inlining
   the tokens is byte-for-byte the same rendered result, one fewer request.
   --pad differs intentionally (flat 20px here vs. styles.css's responsive
   15/20/22px) and stays local to each file.
