Generate an SVG as a graduation congratulations greeting card illustration. Clean minimalist style. White background. Draw a single mortarboard cap outline centered — flat top rectangle, cylindrical sides, tassel as a thin line with small end circle. Stroke in warm charcoal (#4B5563, stroke-width 1.5). Add a minimal laurel leaf pair on each side. Four small dot shapes in #9CA3AF scattered. No fills, generous white space. No text, no labels, no emoji. Output raw SVG code only starting with <svg.

The image shows a black and white graduation cap icon on a white background. The cap is outlined in black and has a tassel hanging from the top.
