// Phase G8d — Haunted Manor of Blackspire branching graph.
//
// T3 zone. Shape: stacked 3-way "hub" forks. The plan calls T2+ for
// "two forks", and a Manor of corridors and locked doors fits a wide-
// fork hub-and-spoke pattern more naturally than a binary fork. Two
// hub nodes (great_hall, upper_hall), each with three options:
//
//   entry → foyer → great_hall (3-way)
//                      ├─[unlocked]── portrait_gallery ─┐
//                      ├─[Perception DC 14]── study ────┼── upper_hall (3-way)
//                      └─[INT DC 14]── library ─────────┘     ├─[unlocked]── master_bedroom (elite) → boss
//                                                              ├─[Perception DC 15]── hidden_oratory (secret) → boss
//                                                              └─[LevelMin 7]── tower_observatory → boss
//
// Two consecutive 3-way fork prompts make this the first zone where
// the player picks twice in a row from a wide menu — distinct from the
// binary forks of G8a/b and the parallel Y-trees of G8c. Exercises
// LockLevelMin (first authored use) so all four non-trivial lock kinds
// (Perception, StatCheck, LevelMin, plus implicit LockNone) appear by
// G8d.
