/* ============================================================
   BLOODSTRIKE GIVEAWAY — Season 18
   Design: "event screen" — dark tactical surface, one amber
   accent, red reserved for live/CTA. Rarity tints on rewards.
   Motion budget: slideshow + ticker only (ambient), the rest
   answers user action.
