The signature

Content is shown as its own source: a mono buffer with a numbered gutter on deep navy, where colour is syntax, not decoration. Pink for headings, cyan for keys, peach for numbers, violet for markers and a violet band for the current line, all on a violet title bar. A clean geometric sans runs the chrome around it.
