Fix Animation Drift

The Sprite Centerer detects each frame bounding box and aligns frames to a shared center X and baseline Y, with manual anchor adjustment when needed. Direct file processing through registry agents is not enabled.

Use cases

• Pixel artist has a wobbly walk cycle

  An artist's character animation wobbles because frames drift off-anchor.

• Stabilize a character walk cycle

  Use Aether Engine when a walk, run, or idle cycle visibly jitters because the character shifts between cells.
