/* SancharAI — cyan on near-black, matching the VoiceAI design language.
   Plain CSS, no build step.

   Variable NAMES stay stable across re-skins (--primary, --green, --red…)
   because page templates reference them in inline styles. Re-theming means
   changing values here, never hunting through markup. */
