The surface turns dark with light labels and cables and a faint light outline round Java's icons; documentation rectangles become a tint of their colour and texts are drawn towards light; the mode buttons use Java's pictures freed from their grey ground (tools/dark-pictures/make.py); native controls follow color-scheme; the desktop's program windows paint through Java-look tokens whose light values are Java's own. The exported image and the report keep Java's colours. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
