Professional White Background Product-Style Cutout

Transform this photo by cleanly removing the background and replacing it with a pure white (#FFFFFF) studio background. The cutout should be pixel-perfect: clean edges around hair (including flyaway strands), clothing edges, and any accessories. No remnant color fringing or halo effects around the subject. Add subtle natural shadow underneath the subject for grounding (soft diffused shadow, not harsh). The lighting on the subject should be adjusted to match studio conditions: even, bright, flattering. Color correct the subject to look natural against white. The final result should look like a professional e-commerce or LinkedIn headshot taken in a real white studio.
