 * Web chat widget (Session 6).
 * Floating action button + slide-up chat panel. Fully theme-variable driven
 * (matches each clinic's brand) and RTL-aware: the FAB/panel sit bottom-right in
 * LTR (Turkish) and flip to bottom-left in RTL (Arabic). On small screens the
 * panel becomes a full-height sheet.
