+- Consolidate `TxLimits` in the mempool.
+     - Remove `Mempool.`getTxSize`; the snapshot interface contains byte sizes
+       now.
+
+     - Transaction size, block capacity, and mempool capacity are
+       multi-dimensional vectors (`ExUnits`, etc), instead of merely bytes:
+       `TxMeasure`.
+
+     - A transaction cannot be added if it would push any component of the size
+       over that component of the mempool capacity.
+
+     - The mempool capacity override is still specified in terms of bytes, but
+       the magnitude is interpreted via division as a block count, rounded up.
+
+- Pass a correctly-sized prefix of the mempool to the forging functions,
+  instead of its entire contents. The mempool's finger tree is best way to find
+  that cutoff.
