Added
- Automatic, vertically stacked, and horizontally arranged scope layouts.
- Draggable pane dividers and nine layout preset slots.
- A status bar for the live RGB readout, color-pin tool, and transient messages.
- Persistent pinned colors and a selectable comparison reference.
- Assumed-sRGB CIELAB conversion, CIEDE2000 ΔE00, and signed ΔL*, ΔC*, and ΔH* diagnostic terms.
- A performance diagnostics channel.
Changed
- Pinning moved beside the live readout rather than occupying a region-tool position.
- Region terminology was made consistent across menus, tooltips, and the picker.
- Automatic layout uses each scope’s preferred pane shape when choosing a division.
The color-difference components describe a comparison; they do not correspond directly to individual editing controls, and no universal ΔE00 pass threshold is implied. See Color Picker and comparison.
