// Tier 6 "Mythic" post-game zone definitions + region registries (Phase P3).
//
// Five hand-authored endgame zones, each four regions deep, gated behind
// postgameUnlocked. Standards are demoted T4/T5 monsters (the tier
// statement); elites and bosses are the bespoke stat blocks in
// postgame_bestiary.go. Loot entries here are declared but their drop
// mechanics (boss-only signature roll, magicItemEffectOverlay, pity
// recipes) are wired in Phase P5.
//
// Registration runs from this file's init(), which executes after
// dnd_zone.go's init() (filename order), so T6 zones append to zoneOrder
// after T1–T5. Hooks/Atmosphere are TwinBee first-person voice.
