 * to hand-write the way CJO hand-wrote `NODE_PALETTE` as a literal
 * (`nodePaletteData.ts:27-100`). Items with no `category` are grouped into a
 * fallback `"Other"` bucket rather than dropped.
 *
 * @param order Optional category-id ordering. Categories named here come first, in
 *   this order; any remaining categories follow in the order they first appear in
 *   the registry.
