frontend (web frontend router)

Index mapping a web-frontend work area to the skill to load. It routes rather than copies - load the named skill for the actual guidance; the one deliberate exception is the Design quality section below, which lives in-skill (it replaced the removed frontend-design plugin). If you already know the leaf skill, go straight to it and skip this router. The .NET backend has its own index (dotnet); this is the web-frontend side.

Companion, not optional: load typescript for any TS/JS - strict typing, type modeling, modules, async, errors. Every row below is in addition to that language baseline.

Required vs optional. In an Angular project the always-on spine is three skills: this router, typescript (every .ts / .js file), and angular-conventions (the framework layer, on any Angular file) - the convention rule already auto-attaches the latter two on .ts edits. Every other row below is an optional specialist, loaded only when its area is in play - angular-material (Material/CDK), angular-styling (CSS/SCSS), angular-security (hardening a feature), mobile (Ionic/Capacitor) - never up front. A plain non-Angular TypeScript project needs only typescript.
