 # Feature Context: Web App Launcher — MVP
 
 ## Current State
-Fresh repository — no code yet. Only PLAN_PROMPT.md and .gitignore exist.
+Phase 1 (Project Scaffolding & Tooling) is complete. The SvelteKit project is initialized with all dependencies installed (`npm install` succeeds). Config files in place: `svelte.config.js` (adapter-node), `vite.config.ts` (Tailwind v4 + Vitest), `tsconfig.json` (strict), `eslint.config.js`, `.prettierrc`, `components.json` (shadcn-svelte), `prisma/schema.prisma` (SQLite). Docker and CI configs created. Build does not pass yet (Big Bang strategy — expected).
