## First-Time Setup
On **first boot**, the device creates a captive Wi-Fi access point:
- **SSID:** `pumpcontroller`
- **IP:** `192.168.4.1`
- **Port:** `80`


### Steps:
1. Connect to `pumpcontroller` Wi-Fi
2. Open browser -> `http://192.168.4.1`
3. Enter your **home Wi-Fi SSID + password**
4. Device reboots → joins your network
5. Find its IP in your router's DHCP list

That IP becomes your **pump control dashboard**
