# pool_mode controls the coinbase shape and the username validation:
#   solo        default. Coinbase pays the miner (stratum username is a
#               BTC address) minus the operator fee. No PPS accrual.
#   pps         Every block's coinbase carries a BIP300 drivechain deposit
#               output for the configured pool_thunder_reserve_address.
#               Miners authorize with a Thunder address (base58 of a
#               20-byte hash). WARNING: the LayerTwo-Labs enforcer does
#               not credit coinbase-source deposits; this mode produces a
#               well-formed but effectively unspendable OP_DRIVECHAIN
#               output. Kept for shape-validation only.
#   pps-classic Coinbase pays a pool BTC address (pool_btc_address below)
#               as a normal P2WPKH/P2PKH output. Miners authorize with a
#               Thunder address and accrue in pps_credits, same as pps.
#               The operator batches accumulated BTC into Thunder from
#               the admin dashboard.
