Hydrozoa user guide

Task-oriented how-tos for running and using a Hydrozoa head.

Guide	What it covers
DEPLOYMENT.md	End-to-end: scaffold, configure, and run a multi-party head; deposit, transact, and close.
DEPOSIT.md	Build a deposit: the L2 payload (EUTXO ledger) and the L1 deposit tx whose metadata pins the payload’s hash.
L2TXS.md	Build a basic L2 transaction (no mint/burn), including withdrawals and the mandatory tx metadata.
L2MINTING.md	Mint and burn tokens on L2: the transient-token declarations and the metadata a minting tx must carry.
REQUEST-HASH.md	Compute the requestHash every submission carries: the preimage layout, the pinned vectors, and what a mismatch means.

Each of DEPOSIT / L2TXS / L2MINTING has a matching CLI subcommand of the packaged hydrozoa launcher (submit-deposit, submit-l2-tx) that serves as a runnable worked example; the guides walk both the wire format and the CLI.

The reference EUTXO L2 ledger drives an isomorphic ledger with native Cardano transactions — an L2 tx is an ordinary Cardano Transaction, and a deposit is an ordinary Cardano tx plus an out-of-band payload. The guides assume that model.

For the machine-readable request/response shapes these how-tos build against, see the API reference.
