/* RSU CertVerify — restrained navy / white / teal theme.
   The approved transparent logo lives in the navbar (`.navbar-logo`,
   see templates/base.html) — it previously sat in the homepage hero but
   was moved to the navbar so it appears on every page. It renders
   directly against the navy navbar (no backing panel) using a
   dark-background variant (static/img/certverify-logo-dark-bg.png,
   generated by scripts/generate_navbar_logo_variant.py) — the original
   logo's dark lettering is recolored to white in that variant only; the
   shield, checkmark, blue wordmark, and the original file itself are
   untouched. */
