/* ==========================================================================
   STANZA — Costanza Realtors client concierge chat widget
   Self-mounting, CSP-strict (no inline JS; events wired in stanza.js).
   Reuses the storefront brand tokens — navy var(--ink) · amber var(--gold) ·
   Cormorant/Hanken/PlexMono. Everything is namespaced under .sz-* so it never
   collides with page styles. Zero CDN, zero new fonts (the tokens + @font-face
   already ship in app.css / listings.css; tokens carry hard fallbacks here so
   the widget still renders branded if a page omits them).
   Distinctive on purpose: a navy seal-pill launcher with an amber Cormorant
   "S" monogram + glow — NOT a generic round bubble.
