Burrow Brand Source

burrow-owl-icon-master.png is the current generated master for the Burrow app icon. The mark centers a leg-forward burrowing owl in a dark brown/black field with minimal warm brown and gold accents.

The editable source is split by intent:

• burrowing-owl-icon-source.svg is the human-readable vector source.
• icon-layers/*.svg are the transparent source layers used to regenerate the Icon Composer package.
• Burrow.icon is the Icon Composer document. Keep it to three broad raster layers: burrow-ground, owl-figure, and owl-legs.
• burrowing-owl-concept-v2.png is reference art only; do not use it directly as an app icon.

That layer count is intentional. The identifying cue is the long Burrowing Owl leg silhouette, so Icon Composer should receive broad shape planes instead of small decorative SVG layers. Face and spot details are flattened into owl-figure.png; the legs stay in the front layer so they survive small sizes.

Regenerate the Icon Composer layer assets and Apple app icon PNGs with:

for src in design/brand/icon-layers/*.svg; do
  name="$(basename "$src" .svg)"
  sips -s format png "$src" --out "design/brand/Burrow.icon/Assets/${name}.png" >/dev/null
done

Run low-resolution export QA with:

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
• pixel-preview-strip.png, a nearest-neighbor strip for 32px and below
• 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.
