// v2.2 Pulse Toast — E2E behaviour proof
//
// These tests exercise the InsightToast overlay (mounted in the root layout
// at /src/routes/+layout.svelte) via the Settings page's "✦ Preview Pulse"
// button. That button calls `fireDemoSequence()` which pushes 4 synthetic
// toasts directly through the toast store — no WebSocket or MCP backend
// required. This is why the pulse-toast tests are backend-agnostic and
// should run reliably in CI without vestige-mcp.
//
// Coverage:
//   1. First toast appears within 500ms of clicking Preview Pulse
//   2. At peak of the 3.2s sequence, >= 2 toasts are visible simultaneously
//   3. Click-to-dismiss removes a toast
//   4. Hover pauses the 5.5s dwell timer (toast survives 8s hover)
//   5. Keyboard Enter on focused toast dismisses it
//   6. The `.toast-progress-fill` animation is paused during hover
// ─────────────────────────────────────────────────────────────────────────────
