Function render_koi 

pub fn render_koi(
    koi_development: &KoiDevelopment,
    koi_body: KoiBody,
) -> KoiFrame

Render the koi in a centered, fixed swimming pose, colored from its languages on the caller’s chosen body. Contribution totals set its size and how far its colors have come in. The account seed places patches in body coordinates, so growth does not reroll the pattern. Streak marks follow the development’s streaks as of its observation date. Identical inputs produce identical pixels without I/O, clock reads, or input mutation.
