Implementation provenance

• The application is original project code and uses the shared Toolbox SDK packages at version 0.3.0 for its manifest contract, shell, and build checks.
• Colour conversion and adaptation use Color.js 0.7.1. Its MIT licence is reproduced in LICENSES/colorjs.io-MIT.txt.
• The compositing, interpolation, palette, image-sampling, contrast, comparison, gamut, and colour-vision utilities in src/colour and src/palette were implemented for this project.
• CSS Color 4 and WCAG 2.2 were used as public technical specifications. No source code or branded assets were copied from the example websites that informed the feature list.
