webui

Playbook for migrating webui feature-area page templates from Angular Material to @truenas/ui-components (tn-* components). Use when working on any child ticket of Epic NAS-141021 — any "Migrate <area> to tn-*" task — or when replacing any mat-* element (card, button, button-toggle, menu, select, toolbar, tooltip, list, tabs, stepper, expansion, slide-toggle, slider, checkbox, radio, datepicker, dialog, snackbar, table, tree, divider, autocomplete, sidenav, progress-bar/spinner, etc.), ix-empty, info-message notices, or SlideIn-hosted forms with their tn-* equivalents. Contains a comprehensive Material → tn-* component map plus the card, side-panel dual-host, declarative-signal, banner, empty-state, table, button-toggle, test-id, and spec-harness recipes established by the shares-dashboard pilot (NAS-141074) and the audit-page migration (NAS-141063).
