# Caption separator opacity — review corrections

Native output from the final review-correction gate. Peaks are the brightest RGB channel within the isolated separator/year glyph rectangles; JPEG edge overshoot and native rasterisation affect the reference/native ratios. The CSS applies `opacity: .4` to the existing muted colour: Compose multiplies the muted token alpha by the generated `captionSeparatorOpacity` token, rather than replacing its existing alpha.
