   The gray/green/amber/red/blue ramps, radius, and shadow tokens were never
   defined anywhere, so ~276 `var(--cert-*)` references were resolving to IACVT
   fallbacks (borders dropping, backgrounds going transparent, square corners).
   Rather than migrate every call site, we alias the ramps here: neutrals +
   greens map to the theme-aware --t-* tokens (so they adapt to dark
   automatically — :root carries the theme attribute); amber/red/blue use
   literals since --t-* has no semantic warning/danger/info equivalents.
   Defined at :root (not .cert-page) so layout-level elements that render
   outside a .cert-page wrapper — e.g. the results.astro loading spinner, which
   mounts directly in CertLayout's .cert-main-content — resolve them too. Live
   impact was concentrated on the leaderboard (bar chart, expand rows, delta
   arrows, dark tables), the loading spinner, and results; this repairs all of
   them with no markup changes. */
