Retro Anime Summer Sports

Create a female summer-sports character in a true late-80s to mid-90s anime/cartoon look, tuned for merch, camp graphics, beach posters, and t-shirts. This prompt pushes away from modern glossy anime and toward vintage cel-era features: chunky ink lines, flat cel colors, simple facial construction, big expressive eyes, glossy hair blocks, and classic sporty poster-girl energy.
