Estimated code review effort: 3 (Moderate) | ~20 minutes Merge Risk: 🟡 Moderate · up to The new spring and vector tween APIs can keep scheduling animation frames indefinitely for invalid inputs, and vector tweens may emit NaN coordinates; the current head should not merge until these inputs are validated and zero-duration behavior is handled.

Require a finite positive precision.
If precision is zero, negative, or NaN, the comparisons at Line 33 cannot settle. Each target update then leaves the RAF loop active indefinitely.

‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

Reject invalid duration values before scheduling frames.
A negative or infinite duration keeps progress below one and schedules RAF callbacks indefinitely. A NaN duration emits NaN vector coordinates. Require a finite positive duration, or handle zero as an immediate update.
