Hover the preview to widen the color fringe.
Red and cyan channels split apart at the edges, a subtle RGB fringe that widens on hover.
Chromatic Fringe offsets red and cyan drop-shadows behind the image to fake RGB split / chromatic aberration, with a wider fringe on hover or focus. Tune --ifx-fringe for the resting offset and --ifx-fringeh for the hover offset (keep both small — 1–4px reads as tasteful rather than broken), plus --ifx-duration and --ifx-ease for the transition. The resting fringe is always visible, so it stays static and legible on touch and under prefers-reduced-motion; keep the @media (hover) wrapper and :focus-within selector so keyboard users get the hover state.
Modern evergreen.
