How it works:
1. Half your cbBTC mints BTC-T at exact 1:1 (the Bitcoin tree fund — its Aave yield funds real trees)
2. Both halves go into the ±5% concentrated band on the 0.01% cbBTC/BTC-T lane — the pool that holds the peg
3. Concentration means each dollar earns like ~40 full-range dollars when the lane trades
4. Compound claims tree-fund yield + lane fees and deepens everyone's position
5. Withdraw anytime — always paid in pure cbBTC (BTC-T redeems 1:1 at the fund)
