- Replace flat kind/secondaryKind model with named BOSS_PROFILES that each carry their own move list, speed multiplier, and attack cooldown, so later fights are harder along every axis at once.
- Add six new attack patterns (ring, spread, spiral, aimed, wall, reinforce) dispatched via round-robin; bosses under half health can swap to a harder phase2Moves set.
- Surface the boss name in the WARNING banner and extend its display time.
- Extend verifyDefender.js with check 10: asserts HP/cooldown monotonicity, valid move names, dual-phase presence, and live-simulates each level's boss to confirm declared move ordering and phase-2 takeover.
