     parity loop (check-renderer-sync only parses styles.css), so defining these
     here triggers ZERO theme-parity work.
     The STRUCTURAL tokens (radius/space/type/motion) are theme-agnostic and live
     here. The accent-derived tokens (--accent-grad/--surface-glow/--ring) are
     defined per-theme on body.theme-light / body.theme-dark below: a custom
     property's inner var() resolves against the element it is DECLARED on, and
     --color-accent/--color-text live on the theme class (not :root), so these
     must be declared there to pick up the live theme palette. Every accent value
     is derived via color-mix() from the theme tokens, so a tenant's Design-019
