Stick QC Test
Step 1: leave both sticks completely untouched and run the 3-second neutral test.

Neutral measurements use raw browser Gamepad API values while the sticks are untouched.
For the range test, move each stick fully left, right, up and down, then make several slow complete circles.
Outer-radius figures only use samples at radius 0.75 or greater. These are QC measurements, not manufacturer-certified limits.

Spin each stick slowly around the full outer gate.
Uniformity Error = how evenly shaped the stick circle is.
Unit Circle Error = average distance from ideal radius 1.00.
Average Radius = average outer radius. 1.00 is nominal; above 1.00 means overshoot, below 1.00 means undershoot.
At least 90% angular coverage is required.
These are circularity measurements, not deadzone percentages.
