 * Schema Commander – product site. One stylesheet for all pages, no web fonts, no external requests.
 * Colours are the app's own tokens (src/styles.css). The page reads like the client it is about:
 * every section is a statement with a line number and a keyword, the pictures are small scenes
 * drawn in HTML with the colours of the app – so they follow the colour scheme, and the scheme picker.
