Workstream 1: Projekt-Fundament & Design-System (Phase 0)

Greenfield-Next.js-15-App-Router-Gerüst (TS strict) mit:
- Route-Groups (auth)/(app) inkl. loading/error/not-found je Group;
  Guard-Slot-Kommentar im (app)/layout.tsx (vom Auth-WS zu füllen).
- "Amtlich"/Netzknoten-Designsystem: Tailwind-Tokens (Navy #1B3A5B,
  Signalrot #E2231A, Anthrazit, Nebelgrau, bereit/Wartung), tabular-nums,
  Serif-Display/Inter-Sans via CSS-Variablen, Inline-SVG-Logo.
- Radix-Basiskomponenten (button/input/label/badge/tabs/dialog/select/
  switch/slider); StatusBadge entspricht asset_status.
- Kanonisches src/lib/env.ts (Zod, Fail-Fast) mit ALLEN DB-/Auth-/Geo-Slots
  inkl. AUTH_URL; isHttps-Ableitung. Zentrale i18n-Tabelle de.ts + t().
- Drizzle-Setup: client.ts (Pool-Singleton), leeres schema/index.ts-Barrel
  (KEIN Migrations-Eigentümer), drizzle.config.ts, .env.example.
- next.config.ts: output:standalone, experimental.authInterrupts,
  Security-Header. Vitest + Fail-Fast-Env-Test (TDD, 5/5 grün).

Bewusst KEINE Auth-Logik und KEINE fachlichen Tabellen.

Verifikation: typecheck/lint/test grün; npm run build erzeugt
.next/standalone/server.js; curl /anmelden -> lang="de" + FlorianNetz.
next/font/google durch CSS-Variablen ersetzt (air-gapped-Build).
