// Sunken Temple of Dar'eth branching graph.
//
// Long-expedition plan D1-b: extended from the original 10-node sketch to
// the new T2 length band (16–20 rooms traversed). Topology preserves the
// G8c design intent — sequential forks with no mid-path merge — and adds
// the missing Trap anchor + deeper pre-fork and per-leaf chains. The
// four leaf chains still terminate at the single boss room (validator
// requires exactly one boss).
//
//   entry → flooded_atrium → tide_passage → kelp_trap (TRAP) →
//   barnacled_steps → drowned_atrium → sunken_nave → fork1
//                  ├─[unlocked, w=1]── dry_corridor → silent_columns →
//                  │     echoing_vault → fork2a
//                  │           ├─[unlocked]── kuo_toa_pen (ELITE) →
//                  │           │     trophy_pool → idol_court → boss
//                  │           └─[STR DC 13]── glyph_chamber → silt_arch → boss
//                  └─[Perception DC 13, w=2]── submerged_passage →
//                        coral_lattice → drowned_nave → fork2b
//                              ├─[unlocked]── aboleth_thralls →
//                              │     thrall_basin → sodden_hall → boss
//                              └─[Perception DC 15]── coral_reliquary (SECRET) → boss
//
// Distinct from the Crypt diamond and the Forest asymmetric-diamond: no
// two paths share a mid-node, so the !zone map paints two parallel "Y"
// subtrees instead of a converging branch. Longest entry→boss = 16.
