Changes: native browser range controls; responsive spacing; keyboard labels; explicit response confirmation; same-origin message delivery. Software metadata was removed from the original endpoint graphics and intensity cue; their pixels are unchanged. Both dimensions are presented together, in randomized order, with a grayscale palette, centered initial thumbs, 0-1 scales and 0.01 steps. Untouched defaults are not submitted.
