rem ============================================================
rem  Non-interactive launcher for Task Scheduler / boot auto-start.
rem  Differences from start-backend.cmd (which is meant for a human):
rem    - no "pause" at the end (nobody can press a key during boot)
rem    - all output goes to app.log next to this file
rem    - resolves java via JAVA_HOME first, then PATH
rem    - exits 0 immediately if port 8090 is already listening
rem  ASCII-only on purpose: cmd.exe reads this file with the OEM
rem  code page, so non-ASCII text here would be garbled.
rem  Registered by install-autostart.ps1; run under the account that
rem  owns the deployment folder (SYSTEM by default).
