// Phase G8b — Forest of Shadows branching graph.

// T2 zone. Per plan §G8 ("two forks for T2+") and the G8 design
// session: deliberately a different shape from the Crypt diamond.

// Shape: asymmetric main fork + WIS-gated secret pre-boss.

// Asymmetry: long branch is two mid-nodes (grove_descent → dryad_circle
// (elite)), short branch is one (thorn_tunnel). Map renders the long
// branch as a "+1 column" arm so the topology reads at a glance.
// Secret uses LockStatCheck WIS (not Perception) to exercise the
// stat-check lock kind — Crypt's secret is Perception, so this is the
// first authored zone using stat_check.
