/**
 * Tena Chat Widget Styles — MADAR Technical Monochrome Design System

 * Theme colors are injected via CSS custom properties by widget.js:
 *   --tw-bg      Widget background (e.g. #0A0A0A deep black)
 *   --tw-text    Widget text (e.g. #F5F5F5 soft white)
 *   --tw-accent  Accent/send button (e.g. #C0C0C0 light silver)
 *
 * Fallback values match the default MADAR dark palette.
