// Forest of Shadows branching graph.
//
// Long-expedition plan D1-b: extended from the original 9-node sketch to
// the new T2 length band (16–20 rooms traversed). Topology preserves the
// G8 design intent — asymmetric main fork (long branch carries the
// elite) + WIS-gated secret hanging pre-boss — and adds the missing Trap
// anchor + extra exploration on both arms and the boss approach.

// briar_warren). Longest entry→boss walk = 16 (long branch path).
