   Scoped to .rr-chat-root and chat-* utility classes.

   No physical left/right properties anywhere — all directional CSS uses
   logical equivalents (inset-inline-*, padding-inline-*, margin-inline-*,
   border-*-radius logical corners, text-align: start/end). The widget
   auto-flips for RTL based on the document's `dir` attribute.
