max_send_lovelace default is now network-aware: mainnet 10 ADA,
preprod/preview 100 (t)ADA. Mainnet handles real value, so the cap
should bite earlier — anything > 10 ADA needs explicit force=true.
Test ada on preprod/preview is faucet-replaceable, no need to
sand off the test surface. New regression
mainnet_default_max_send_is_tighter locks the rule in.
PLUTUS_V3_COST_MODEL_PREPROD docstring updated: confirmed identical
to mainnet PV3 cost model (preprod epoch 286 = mainnet epoch 629,
both 297 params, byte-identical). Cost models are protocol-version
parameters, not network parameters; using the same constant on
both is correct. Re-snapshot from mainnet Koios after any major
hard fork. Naming kept as _PREPROD for git churn reasons.
