90s Yearbook Portrait

Transform this photo into an authentic 1990s American high school yearbook portrait. Preserve 100% accuracy to subject's face while applying era-appropriate styling. The photo should have: classic mottled blue/grey gradient backdrop, soft diffused studio flash lighting, slightly overexposed with lifted blacks, characteristic 90s film grain and subtle color shift. Hair should appear slightly feathered or have that "mall hair" volume if applicable. Add subtle vignette and the specific softness of 90s portrait lenses. Colors should feel warm but slightly faded like photos that have aged 30 years. Include the characteristic yearbook border/frame. Expression should be that slightly awkward but genuine yearbook smile. The final image should look indistinguishable from a scanned yearbook photo from 1994.
