Multi-Data Composite
One token receives a normalized packet from multiple feeds.

- competition
- editionHash
Preview and metadata only until Mike signs a Tezos origination or mint transaction.
Live feed values are captured into metadata at mint time; the token should not depend on mutable upstream APIs.
One feed snapshot drives the whole card: weather, sea, or competition.
A normalized packet combines feed snapshots and stores the composite checksum.
