Floating panel in bottom-right of all dev targets lets you: - Switch presets (Purple, Blue, Neutral, Warm, Rose, Emerald) - Adjust gray hue/saturation and accent hue/saturation with sliders - Preview color swatches in real-time - Copy EDN config to paste into tokens.edn State persists in localStorage. Panel collapses to a small toggle button. Hiccup handler changed to use #'handler var for hot-reload.
