@kieransimkin these submissions look smart together on the nft and hosted pages (plus elsewhere for the NFT Playground) and demonstrate complementary implementations of the progressing CIP-0054 (cardano-foundation/CIPs#895) so as I see it are crucial to be offered to builders via the Portal.

@katomm it seems all prior reservations have been resolved & so this submission should be OK to go ahead now.
