Crate animation freezes on first key use

The first crate opening sometimes pauses before the reward animation completes. The reward still appears, but the initial visual sequence feels delayed and unfinished.

• Most commonly reported after a fresh login or first crate interaction
• Likely related to animation preload timing or delayed visual assets
• Reward delivery still completes after the animation catches up

This issue does not appear to affect rank delivery or purchased rewards, but it should still be resolved for a cleaner player experience.
