Module screenshot 

Headless offscreen screenshot capture for modde’s hottest GUI screens.

This module renders fully populated demo screens to RGBA pixels and PNG files without a GPU or display server, using iced 0.14’s dual-backend iced_test::renderer::Renderer, which falls back to the pure-CPU tiny-skia backend when no GPU is present. It powers the hidden modde dev screenshot CLI command used to generate Flathub / website assets and (in the future) CI automation.

The whole module is gated behind the non-default screenshot cargo feature so release binaries carry zero extra weight.

Screens are driven by constructing a demo Modde and setting its state fields directly — never by dispatching update() messages, which would fire async Tasks that need a database or network.

For determinism, run with ICED_BACKEND=tiny-skia in the environment so the software backend is always selected.
