       shared.css (no design-system) still get the AscendMed gold defaults.
       The body.track-* override blocks live in ascend-design-system.css.

       See ascend-design-system.css for full documentation. Note:
       --accent-glow, --accent-bg-tint, and --gold are literals (not var())
       because nested var() in a custom-property value resolves at the
       declaration site, not at the use site, breaking track switching.
