Extract the install that was applied by hand to the Jetson Nano into a single checkout that builds itself for whatever Jetson it lands on. The two nodes on the rig share no JetPack — tegra210 caps at 4, tegra234 needs 5+ — so nothing binary is portable between them. The source and the procedure are: install.sh detects the platform (L4T / JetPack / SoC), installs deps, builds the OrbbecSDK and the preview server from source locally, and generates a per-user config and systemd unit. The tested bridge.py ships verbatim; all machine-specific paths live in the generated config, so it stays unmodified — its one hardcoded path is made home-relative. The retired GStreamer/RTSP target is dropped: the direct route encodes no video. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>

# 1. An existing build pointed to by $OB_SDK_ROOT — reused as-is. This is what
|
|
# keeps a working node (the Nano already has one) untouched.
|
|
# 2. A build at one of the known locations, likewise reused.
|
|
# 3. A fresh clone + build. On a new JetPack this is the step to watch; if it
|
|
# fails, build the SDK by hand once and re-run install.sh with OB_SDK_ROOT set.
