/* ============================================================
   Uptimia — Free HTTP/2, HSTS & IPv6 Protocol Checker (/http-protocol-checker)
   Ported from docs/http-protocol-checker-mockup.html <style> block.

   EVERYTHING is scoped under the root wrapper `.hpc` so it can
   never collide with homepage-v30.css / tools.css (both also
   loaded on the page). The mockup's :root custom properties live
   on `.hpc` instead of :root; generic @keyframes (pulse/rot) are
   renamed hpc-pulse / hpc-rot. The mockup's own site chrome
   (.topbar / .nav / .brand / .dock / .foot) is intentionally
   dropped — the real page provides top_menu + footer. Fonts are
   NOT imported here; the site already loads them and we rely on
   the mockup's font-family stacks. A `.hero-error` banner and the
   `bad`-tone variants (verdict bad-mode, badge-bad, sb/tstep/val
   bad) are added to match the sibling + the render model (§7) —
   the mockup only ever drew the warn/ok result states.
