/* Sonar front end — mirrors the report brand (src/sonar/report/templates/brand.css)
   exactly: light, airy, white cards on off-white, blue hairlines, no black
   shadows (tinted blue only). The spectrum gradient is the one luminous
   signature — it appears ONLY on the score band and the primary CTA. Amber means
   one thing: "validated against source".

   Fonts are served from /assets/fonts/ (the FastAPI app mounts the report's
   assets dir there); no CDNs, no build step. */
