// Phase G8f — Feywild Crossing branching graph.
//
// T4 zone. Shape: woven forks — two first-stage forks each lead to a
// second-stage fork; the inner nodes partially overlap so the player's
// first choice does not fully determine which second-stage rooms they
// can reach. Captures the Feywild theme of "the path you walked is
// not the path you arrived on."
//
//   entry → twilight_path → fork1
//                             ├─[CHA DC 14]── glamoured_grove ─┬─ hag_circle (elite) ─┐
//                             │                                └─[DEX DC 15]── time_eddy ─┤
//                             │                                                          ├── boss
//                             └─[Perception DC 14]── wisp_marsh ─┬─ hag_circle ──────────┤
//                                                                └─[Perception DC 16]── illusion_garden (secret) ─┘
//
// hag_circle is reachable from BOTH first-stage paths — the elite
// encounter is the "you'll meet her either way" room. time_eddy is
// only reachable via the grove (CHA path); illusion_garden is only
// reachable via the marsh (Perception path).
//
// First authored zone using LockStatCheck CHA — every prior secret/
// gate has been Perception/STR/INT/DEX. Both fork1 entries are locked
// (no LockNone option from fork1) which is the first instance of "no
// free choice"; the player must commit to the lock-check style they're
// stronger at.
