/* =========================================================================
   Chatbotistic V4 compat bridge
   -----------------------------
   The V4 design system (v4-styles.css / v4-portal.css) is the canonical
   source of truth for the look and feel. It uses unprefixed selectors:
   .btn, .card, .container, .section, etc.

   The existing PHP templates render with the legacy `cb-` prefix:
   .cb-btn, .cb-card, .cb-container, .cb-section. They predate V4.

   Rather than rewriting every PHP template (high blast radius), this
   bridge file aliases the prefixed names onto V4's unprefixed rules
   via the @extend-style pattern: every cb-name simply mirrors the
   shorthand version. The result is one canonical V4 ruleset with two
   entry points.

   This file MUST load AFTER v4-styles.css so its rules can reuse
   anything V4 defines via custom properties.
