Compare Reveal

compare-reveal

A before/after comparator whose divider chases the pointer through a spring (k=140, c=18, ζ≈0.76) so the lag reads as elastic resistance, demonstrates itself once on first viewport entry (50 → 96 → 4 → 50 over 2.6s), and snaps home on double-click. Coral signature handle; real slider semantics with 2% / Shift 10% arrow steps.
