Tilt Shift fakes a miniature-diorama look: a sharp horizontal focal band with the rest of the photo softly blurred and slightly saturated, as if shot with a tilt-shift lens. A ::before duplicates the image via the --ifx-src custom property — set it on the figure to the SAME url() as the img's src (the generated HTML/React does this for you) — and a masked gradient band lets the untouched, sharp <img> show through the focus zone. Tune --ifx-ts-focus (vertical band center), --ifx-ts-band (band height), --ifx-ts-feather (edge softness), --ifx-ts-blur (blur strength) and --ifx-ts-sat (surround saturation). Fully static: identical on touch and nothing to reduce for prefers-reduced-motion.
