+This is a Cargo workspace; each Soroban contract is its own crate under
+`contracts/`.

 ```
-src/
-  lib.rs              Contract entry point — all public functions
-  liquidity_pool.rs   Pool math: optimal amounts, K-invariant, LP mint/burn
-  lp_token.rs         Internal LP ledger: mint, burn, transfer, approve, allowance
-  math.rs             AMM formulas: get_amount_out, get_amount_in, sqrt
-  storage.rs          DataKey enum for all instance + persistent storage keys
-  events.rs           Soroban event wrappers: Mint, Burn, Swap, Sync
