Build Notes: Originally planned as Njord sensor hub (GPS, environmental monitoring). Pivoted to photo display after realizing the hardware is perfect for a van-mounted slideshow. May add sensor logging later as Phase 2. Display will cycle through chicken and duck photos stored locally on USB or pulled from home server via Tailscale.
