Categories & assets
Drop PNGs onto a category to add them. The file name becomes the
asset name (e.g. fox.png → fox). Thumbnails are made
automatically — hover an asset and click 🖼 to set a custom one.
Layer order
Drag to reorder. Top of the list = drawn first = furthest back. Bottom of the list sits in front of everything.
Dependencies
A dependent category only shows options whose name starts with the
chosen base asset's prefix. Example: tail_markings depends on
tails, so picking the long tail only shows
long_* markings.

Color swatches
Optional. Add hex colors to a category to offer recolor swatches in
the app (the app expects matching name_color.png files).
