/**
 * Boss signature attacks: the one memorable thing each boss does.
 *
 * Boss review 2026-09-29 (dreadwoods/.cursor/task-plans/2026-09-29-boss-presentation-review.md):
 * only the dragon had a mechanic; every other boss was stats. A signature is
 * the dragon's pattern made general: every Nth attack of the boss is its
 * signature, announced a full turn ahead (`combat_windup` with
 * `attack: 'signature'`), so a player can see it coming and know which boss it
 * is. The server rolls and applies it (dreadwoods-backend src/bossSpecials.ts,
 * hooked into the NPC turn through dragonfire.ts); the client draws the tell
 * (dreadwoods-frontend src/render/BossTellFx.ts).
 *
 * Budget-neutral by construction: over one cycle of `every` attacks, the
 * ordinary hits are scaled down by (every - mult) / (every - 1) and the
 * signature hits `mult` times an ordinary roll (through the same hit chance),
 * so the expected damage per cycle is what the boss did before. Only its
 * shape changes: fewer, heavier, telegraphed blows. No health pool grows.
 *
 * Three exceptions to "every Nth attack":
 * - `guard` (Frost Warden): a guard turn hits ordinarily and then parries the
 *   player's next swing. Its health is trimmed by GUARD_HEALTH_SCALE to pay
 *   for the swings it costs.
 * - `shatterAt` (Glacial Behemoth): a crystal on its back shatters at those
 *   health shares; the next attack is announced and heavy, and its ordinary
 *   hits are lighter (`ordinaryScale`) to pay for the four shatters.
 * - `poolScale` (Blood Mire Elemental): its blows scale with how much of its
 *   pool is left, which is also how the client draws the pool draining.
