Subject: [PATCH] [#261] Fix royalty ABI: correct parameter order and return
 values
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- getRoyaltyInfo: fix inputs to (wallet, reserveToken), outputs to
  (balance, claimed) — was (token, beneficiary) → single uint256
- claimRoyalties: pass reserve token (PLOT_TOKEN) not storyline token
- ClaimRoyalties.tsx: swap args, destructure [balance] from return,
  use PLOT_TOKEN for both read and claim calls
