REM bootstrap.bat
REM
REM Single-file installer / updater / launcher for TrussLeafAssembly.
REM Send THIS file to the steel detailer. They double-click it:
REM
REM   First run:
REM     - Installs Git if missing (via winget) or links to download
REM     - Asks where to install (default ~\Projects\TrussLeafAssembly)
REM     - Clones the repo (PAT entered via Git Credential Manager
REM       when Git prompts for credentials -- send the PAT separately)
REM     - Saves the chosen path to %APPDATA%\TrussLeafAssembly\install-path.txt
REM     - Calls update.bat: prereqs + pull main + build (no launch)
REM     - Creates two Desktop shortcuts:
REM         "TrussLeafAssembly"        -> TrussMaui.exe (direct launch)
REM         "TrussLeafAssembly Update" -> repo\update.bat
REM
REM   Every run after:
REM     - Reads the saved path from the state file
REM     - Re-runs update.bat (pull + build) and refreshes the shortcuts
REM
REM The .bat can live anywhere -- on a network drive, the detailer's
REM Desktop, etc. After first run, daily use is via the Desktop shortcuts.
