"""
Admin Peers page — WireGuard peer management UI tests.

Scenarios:
  8. Create peer via UI → one-time password modal ("Peer Created — Save This Password")
  9. Delete peer via UI → peer disappears from the table

Key selectors confirmed from Peers.jsx:
  - "Add Peer" button: button with text "Add Peer" (Plus icon + text)
  - Name input: input with placeholder "mobile-phone" (no autocomplete attr; class="input")
  - Password input: type="password" autocomplete="new-password"
  - Generate (password) button: button text "Generate"
  - Submit button: button text "Add Peer" (type="submit" inside the modal form)
  - Password modal heading: "Peer Created — Save This Password"
  - Done button in modal: button text "Done"
  - Delete button in peer row: button title="Remove Peer" (Trash2 icon)
  - Confirmation: window.confirm() — Playwright auto-accepts dialogs unless overridden
