CRED Button Loader Animation

An OTP verification screen features a black primary button containing a unique loading indicator. Instead of a standard spinner, the loader consists of four white square dots. When verifying, these dots stretch vertically into colorful bars (green, purple, and white) that bounce up and down with varying heights, mimicking an audio equalizer. Once the loading cycle pauses or completes, the bars smoothly shrink and morph back into four static white squares.
