/* Ecopia webchat widget -- CP4. Self-hosted, zero CDN.
 * Replaces the Coze SDK. Design tokens taken from the site:
 *   #16a34a brand green, #f9fafb panel grey, #e5e7eb borders.
 * Positions match the old Coze block exactly so the page looks unchanged:
 *   launcher right 80px / bottom 100px, panel right 80px / bottom 180px.
 * All selectors are prefixed ecw- to guarantee no collision with the
 * React bundle's own class names.
