+"""Screenshots for docs/screenshots with the desktop build (no browser needed).
+
+1. `cargo test --release --bins export_scenes -- --ignored` writes the scene savegames to /tmp/scenes.
+2. `cargo build --profile desktop`
+3. `python3 tools/shots_desktop.py [--style hd|pixel] [names...]` runs the game once per scene with
+   DC_SHOT (see the self test in src/main.rs), makes its window float at 1280x800 (Hyprland), and
+   writes docs/screenshots/<name>.png scaled to 1280x800. `title` is the title screen.
+Needs Pillow (for the scaling) and Hyprland's hyprctl.
