/* ═════════════════════════════════════════════════════════════════════
   SocialChat Ultra — customer widget
   Scroll strategy: the messages container is a plain BLOCK element with
   min-height:0 inside a concrete-height grid cell and overflow-y:auto.
   No flex scroll tricks. Do not replace with flex — three previous
   attempts all failed because flex items ignore max-height in practice.

   Mobile strategy: under 480px the panel goes full-screen (fixed, inset 0)
   and sizes itself to --scu-vvh — the *visual* viewport height kept fresh
   by widget.js — so the iOS/Android keyboard never hides the composer.
   All text inputs are ≥16px on mobile to stop iOS focus-zoom.
