## The shape to store

Save explicit selections and colors when the user edits an avatar. Save a seed when the avatar can be regenerated from user identity.

```ts
type HumationAvatarState = {
  seed?: string;
  selections?: {
    head?: string;
    body?: string;
    bottom?: string;
    item?: string;
    glasses?: string;
  };
  colors?: {
    hair?: string;
    clothes?: string;
    bottom?: string;
    skin?: string;
    stroke?: string;
    background?: string;
  };
};
```

For long-lived saved data, canonical IDs such as `hm1-p-000020` are the most stable. Human-readable names such as `braids` are convenient for code and prompts.
