A web app to track flower pots and receive reminders when each pot is due for watering. Backend REST API plus a frontend UI.

• Add / remove flower pot — a pot has a name, species, and a watering interval in hours. Pots are persisted on the backend and managed both via the REST API and the frontend UI.
• Receive notification about watering time — the backend computes which pots are overdue based on last_watered_at + watering_interval_hours and exposes them via GET /api/notifications; the frontend surfaces them in a notifications panel.

Player prerequisites

Task probes run on the joiner's machine and drive the app through a fixed contract — make sure the environment has:

• Node.js + npm — probes boot each workspace with npm --prefix <workspace> run dev -- --port <port>, so both backend/ and frontend/ need a dev script that honours a --port argument.
• agent-browser — the frontend tasks are verified through a headless browser (npm i -g agent-browser && agent-browser install).
• sqlite3 (optional) — used to validate the schema file when present.

The frontend receives the backend's port via the BACKEND_PORT / VITE_BACKEND_PORT environment variables; proxy /api requests to http://localhost:$BACKEND_PORT in the dev-server config. Each task's description spells out its exact acceptance contract.
