# deploy-server build-android.sh + cyc.sh x11-server (swaps the APK lib, RESTARTS the session)
# check the evidence: Xwayland took glamor (journal), its MobileGL log, GLX's path
# line, dma-buf counts in Xwayland/KWin, the server's import lines
# apps xterm + xeyes + glxgears on screen, two screenshots (hashes must differ)
# apps X11 clients on screen: konsole and kate on Qt's xcb platform (glamor-drawn
# core X), glxgears (GLX), xterm/xeyes when installed; two screenshots
# stop kill the test apps
#
# Typical run: preflight; measure before; deploy-client; deploy-kwin; deploy-server; check; measure
