 * imported here because this is a static site with no build step and nothing to resolve an
 * @import across repositories — but the values are the terminal's and should be changed there
 * first. The verdict ramp is not carried: this page does not render verdicts, and a palette that
 * ships colours nobody uses invites somebody to use them wrong.

 * Fonts are self-hosted in ./fonts/ (copied from the @ibm/plex-* packages via podcast-admin). No
 * font host, no CDN, no analytics — which is what lets netlify.toml set `script-src 'none'`.
