 ## Validar pós-deploy VM122
 
 - [ ] `/assets/tickets-workspace.js` HTTP 200
+- [ ] `/assets/tickets-workspace.css` HTTP 200
 - [ ] Vista Tickets: 8 KPIs visíveis
+- [ ] Cards alinhados (100% largura, sem quebra lado-a-lado)
 - [ ] Clicar ticket → abas Resumo | Funil
 - [ ] Filtro chips Live / Parados funciona
 - [ ] Ctrl+Shift+R após deploy
 
+## Blindagem CSS (2026-06-19)
+
+CSS do Tickets Workspace em ficheiro **isolado** `tickets-workspace.css` — não editar estilos de tickets em `styles.css` global (evita regressões ao deployar INFRA CODE / proc-card).
+
 ## Script deploy
 
 `/opt/ligbox-spec-hub/scripts/deploy-tickets-vm122.sh`
