#TODO: Qt6 Graphs — cross-compiled for Redox against the Qt 6.11 Qt Quick/QML substrate. This recipe intentionally builds the validated 2D graphs surface first; the 3D graphs path stays disabled until the Qt Quick 3D substrate is ready in-tree.
# Provides: libQt6Graphs and the QtGraphs QML module for 2D graph types.
