# psmux Overlay Rendering Verification Test
# Tests that overlay commands (display-popup, display-menu, confirm-before,
# display-panes, clock-mode) actually produce overlay state in the server's
# dump-state JSON — proving the client will render them.
#
# This goes beyond exit-code testing by connecting directly to the server's
# TCP protocol and inspecting the JSON wire format for overlay fields.
#
# Run: pwsh -NoProfile -ExecutionPolicy Bypass -File tests\test_overlay_rendering.ps1
