      Fonts (match docs.opaque.cash).
      OPQ-031: this Google Fonts stylesheet is third-party and carries no Subresource
      Integrity (SRI) hash — SRI is impractical here because the returned CSS is
      user-agent-dependent, so its hash is not stable. The CSP in vercel.json restricts
      style/font loads to fonts.googleapis.com and fonts.gstatic.com only. To fully remove
      the external dependency, self-host these fonts under /public and drop the two hosts
      from the CSP.
