Scaffold Next.js frontend with generated OpenAPI client and core views

Next.js (App Router) + React 19 + TypeScript + Tailwind v4, with shadcn-style UI primitives (Button, Input, Card, Label via cva/tailwind-merge). A typed API client is generated from the backend OpenAPI spec with openapi-typescript + openapi-fetch (npm run gen:api); the committed openapi.json/schema.d.ts are the snapshot.

Views: landing, login, register, tree list + create, and tree detail with person list + create. Auth rides the same-origin HttpOnly session cookie the backend sets (Caddy proxies /api/*), so no token handling in JS. Built as a standalone container. Mobile-first; next build is clean.
