+## Bundled OpenWorlds icon assets
+
+OpenWorlds vendors a small curated subset of **Game Icons** under
+`viewer/openworlds/assets/icons/game-icons/` for gameplay affordances such as
+attacks, dice, travel, quests, camp, settlements, consumables, and coins.

+- **Attribution:** see `viewer/openworlds/assets/icons/ATTRIBUTION.md`.

+
+The imported SVGs were normalized only for presentation by removing the opaque
+background rectangle so the app can tint them as local CSS masks. ClawDnD does
+not vendor the full icon set and does not fetch icon assets from a network CDN.

+# OpenWorlds Icon Attributions
+
+OpenWorlds imports a small curated subset of [Game Icons](https://game-icons.net)
+from `game-icons/icons`, not the whole repository. The source repository license
+text says icons are Creative Commons 3.0 BY unless a contributor is explicitly
+marked CC0, and asks derivative works to include `Icons made by {author}`.
+
+Imported SVGs were normalized only for presentation by removing the opaque
+background rectangle so the app can color them through CSS masks. The underlying
+icon silhouettes are unchanged.
