/*
 * fab-feedback.css
 * Styles for the FAB feedback widget (Phase 2 Workstream B2).
 *
 * Relies on brand CSS custom properties already defined by the surface's
 * primary stylesheet (--primary, --accent, --bg, --text etc).
 * Loaded after dashmeshtoys/css/brand.css so tokens are available.
 *
 * z-index stack:
 *   9000 — FAB button
 *   9100 — PIN / capture sheets backdrop
 *   9200 — PIN / capture sheets
 *   9500+ — toast (reserved by dashboard; FAB toasts use 9600)
