Backlog: Scaffold Next.js repo + Vercel/Mongo

TL;DR

Create lumendev-museum-ibu-marsinah GitHub repo (single Next.js app), wire MongoDB Atlas, link Vercel (preview + prod), document env vars for local dev.

Description

• Bootstrap Next.js App Router project aligned with [[Resources/Tech/Personal default fullstack stack|LumenDev default stack]].
• MONGODB_URI for local + Vercel prod; separate DB name or cluster per env if needed.
• AUTH_SECRET, AUTH_URL / trust host, Google OAuth client for dev + prod redirect URIs.
• README + AGENTS.md stub pointing to vault hub.

Acceptance Criteria

• Repo exists on LumenDev GitHub; default branch protected as team prefers.
• npm run dev runs locally with .env.local documented (~/Project/lumendev-core).
• Vercel project linked; prod deployment succeeds (hello-world OK).
• MongoDB connection verified from /api/health.

Local scaffold (2026-05-21)

• Path: ~/Project/lumendev-core — git main, no remote (per plan).
• Verified: GET /api/health → { ok: true, db: "connected" } with local MongoDB.
• Deferred: GitHub push, Atlas prod URI, vercel link + prod deploy — see repo README.md § Deferred.

Priority

• p0 — blocks all other items.
