Editing - Color, Structure, Sync

Color bar operations (WarpColor/WeftColor): Always color-only. Never touch structure or thickness. Sync checkboxes are completely ignored. Structure operations (Warp/Weft): This is where Sync matters: - Sync Color ON → operation also affects colors alongside structure - Sync Color OFF → operation only affects structure, colors untouched - Sync Thickness ON → operation also affects thickness alongside structure - Sync Thickness OFF → thickness untouched

This is one-directional — sync only flows FROM structure TO color/thickness, never the reverse.

The following video demonstrates the sync color setting.
