/*
 * CDD AI Assistant — Widget styles
 *
 * Side drawer that slides in from the right edge. Light theme matching
 * collaborativedrug.com (Montserrat, navy text #020B31, brand blue #1262B3).
 *
 * Scoped under #cdd-ai-assistant — every selector is prefixed so styles
 * never leak onto the host page. The host page is HubSpot, which has its
 * own CSS that we must not interfere with.
 *
 * Designed for desktop and mobile (responsive breakpoint at 768px).
