Start9 Frontend · start9labs bundle Start9 house style for every Angular + Taiga UI web frontend (StartOS ui/setup-wizard, StartWRT, StartTunnel, brochure-marketplace, start9-store, ops-server, support-server). Use BEFORE writing or reviewing any frontend code in these apps — components, templates, styles/CSS, forms, dialogs/toasts, routing, state, DI, i18n — and when bootstrapping a new Start9 web UI or upgrading Angular/Taiga. Includes doctrine, recipes, an antipattern catalog distilled from the fleet's refactor history, and a verified Taiga 5 API reference.
