// NOI2017 分身术 — persistent SEGMENT TREE of x-monotone chains (upper/lower hulls).
// Rewrite of the persistent-treap pstfull13: each layer's x-sorted chain is a copy-on-write
// segment tree over the global x-order [0,SZ). Node = {ch0,ch1,first,last,cs} (24 bytes,
// deterministic: no prio/rotation/heap). split = PST path-copy; merge = segment-tree union of
// two disjoint x-ranges (O(log SZ)); tangent = direct O(log SZ) descent on the PST roots; the
// area cross-sum is the node field. Same onion+split/merge/bridge algorithm as pstfull13.
