SVG makes tiny, resolution-independent textures and shapes from a few numbers. Generate a repeating <pattern> tile or a random organic blob, and copy the markup.
One small tile in <defs> fills any area at any size — a 200-byte texture instead of a PNG. Great for hero backgrounds and section dividers.
A blob is a closed path of points placed around a circle at randomized radii, joined by smooth cubic curves. Re-roll for a new one.
This is the same technique behind those "blob" hero shapes — deterministic enough to control, random enough to feel hand-drawn.
