# GUI screenshot validation on Windows — launch the REAL timeglyph-lens window,
# capture just that window, and assert it renders meaningful content (not the
# all-black frame a dropped-font atlas silently produces).
#
# Needs an INTERACTIVE desktop session (e.g. autologon on the GCP/native-x86 test
# VM). A service/headless session has no desktop for the window to appear on, so
# FindWindow returns null. macOS/Linux: use scripts/screenshot-validate.sh.
#
# Writes the PNG to $env:OUT (default %TEMP%\lens-shot.png) and exits non-zero if
# the frame is all-black/uniform.
