REM  postinstall.bat -- runs ELEVATED after TeslaLauncher extracts the zip to
REM  the games root (C:\games). The zip root holds this file + ONE package
REM  folder; this script finds that folder, installs the bundled Npcap, and
REM  hands off to deploy\configure.ps1 for the NIC bind / IP derivation / conf
REM  rendering.  Air-gapped: nothing is downloaded.  See DEPLOYMENT-PLAN.md.
