# Visual cert for Lantern window transparency (task lantern-translucency).

#

# ./run-transparency-test.sh

#

# Opens the static semi-transparent CSS page (examples/transparency-test) in a

# transparent-capable Lantern window. If the Lantern side works, your desktop

# shows through the tinted page background and fully through the dashed cutout,

# while the blue panel stays solid. Zero Slate dependency — isolates the

+10

# GtkWindow RGBA + alpha-0 webview change.

+11

#

+12

# Wraps the invocation in an ephemeral `guix shell` (the GTK4 + WebKitGTK + Mesa

+13

# graphics stack from gl-manifest.scm). If the window never maps, re-run with

+14

# LANTERN_SOFTWARE_RENDER=1 (the Mesa GL loader-path gotcha).
