How SVG blob shapes are generated
Blobs are created by distributing anchor points evenly around a circle, then randomizing each point's radius within a configurable range. The points are connected with a cubic Catmull-Rom spline converted to SVG cubic Bezier curves — producing the smooth, organic appearance. Adjusting the number of points controls how many “bumps” the blob has; irregularity controls how far each point can deviate from a perfect circle.
