+Run low-resolution export QA with:
+
+```bash
+Scripts/check-brand-icon-lowres.sh
+```
+
+The script writes `design/brand/low-res/`, including:
+
+- `burrow-icon-{16,20,24,29,32,40,48,64,80,128,256}.png`
+- `preview-strip.png`, a 256-to-16px visual strip scaled up for inspection
+- `report.csv`, with color-count and grayscale-contrast checks
+
+Sizes that overlap `Apple/UI/Assets.xcassets/AppIcon.appiconset/` should remain
+pixel-identical to the generated app catalog assets.
