/* ============================================================
   CodeRadar design tokens
   Forked from the Goodventures portfolio token system.

   CodeRadar palette choice: "amber-coral" (custom for CodeRadar).
   - --accent: amber #ffb020 — signals "alerting / detection" (radar sweep,
     warning lamp, error indicator). Distinct from RelayGate's cobalt-ember.
   - --warm:   coral #ff5c54 — error/severity secondary. Pairs with amber
     in the same way Sentry uses purple+red, but warmer and more distinct.

   Design ethos: dark + technical. Same Space Grotesk + Inter Tight + JetBrains
   Mono stack as relaygate. Content-page chrome inherits from the shared
   chrome.css/prose.css so visual parity with the rest of the portfolio holds.
