Both capture helpers now accept --out=res://docs/screenshots, and tools/check_screenshots.sh renders the staged set (using xvfb-run when headless) before running screen_designs.py compare. Record the judge result: 7 match, 4 review, 0 diff. Headless 226/226 and the smoke both pass in a clean worktree.

## Dev helper: render every generated prop side by side on a plain backdrop and
|
|
## save user://screenshots/10-prop-gallery.png by default. The image feeds
|
|
## `tools/screen_designs.py compare` so a prop regression is visible.

## Usage: godot --path . --script res://src/test/capture_prop_gallery.gd
