Lens Dock

A dock with true macOS physics: icon size follows a Gaussian bell curve of cursor distance — full magnification under the pointer, easing to 1x at the falloff radius — with each icon growing upward from a bottom anchor so the bar's baseline never moves. One caret tooltip glides between icons via layoutId while a rAF loop keeps it pinned to the live-resizing icon. Separators and an always-visible-labels mode included.
