"""Capture a read-only Agave review in an isolated SDL or TTY session.
python3 test/ui_review.py zig-out/bin/pardes-gui /tmp/pardes-review \\
--project /path/to/agave --theme orchard
Requires rust-analyzer for LSP, an X11 display and ImageMagick for SDL PNGs.
The project files are never written. Cargo build output stays in --cargo-target
(or OUTPUT/cargo-target). Use --skip-lsp when reviewing additional themes.
TTY captures are the actual core grid and styles, not emulator screenshots.
