/* ============================================================
   CODIA TECH — "Signal" design system
   Tokens, reset, base typography, shared utilities.
   Section styles live in assets/css/components.css.

   Colour is taken from the wordmark itself. The violet-to-cyan
   gradient is rationed: it appears on the mark, the live
   indicator, the row sweep, and nowhere else. Everything else
   is ink, hairline and cool white.
