/* 2026-08-01 -- root-cause fix for Boss Rush's encounter card staying
   visible over Runway. The rule above only ever hid Runway's own HUD
   when Boss Rush is active -- there was no symmetric rule hiding Boss
   Rush's encounter UI outside Boss Rush, so a card left in its .show
   state from a prior Boss Rush run (position:absolute, opacity/
   pointer-events toggled only, never display:none) stayed fully rendered
   and interactive on top of Runway regardless of whatever mode-switch JS
   did or didn't clean up. This is authoritative over that JS state:
   display:none removes it from layout flow and neutralizes any lingering
   opacity/transform/pointer-events, no matter which mode the encounter
   card's .show class was left in.
   Scoped to Runway only, NOT Survival -- confirmed in arcade.js
   (updateBossEncounterHud/bossHudKicker) that Survival mode has its own
   real boss encounters and legitimately uses this same card (labeled
   "BOSS ENCOUNTER" there, vs "BOSS RUSH N/M" in Boss Rush) -- hiding it
   in Survival would have broken that real feature, not fixed a bug. */
