After: what comes back

The first lines of a real run on that input. Nothing here is edited by hand.

DESIGN.md score 4/100: 21 words, 3 of 9 expected sections, 3 colours, 1 text and background pairs checked

Sections: ok purpose and audience; missing principles or voice; ok colour; ok typography; missing spacing and layout; missing components; missing imagery and motion; missing accessibility; missing do and do not

HIGH   Text #9a9a9a on Background #ffffff is 2.81:1; text needs 4.5:1
HIGH   no "never" list; the fastest way to stop generic output is naming the defaults you reject (gradients, eyebrow labels, three identical cards)
MEDIUM no principles or voice section; a model has to invent it, and it will pick the default
MEDIUM no spacing and layout section; a model has to invent it, and it will pick the default
MEDIUM no components section; a model has to invent it, and it will pick the default
MEDIUM no imagery and motion section; a model has to invent it, and it will pick the default
MEDIUM no accessibility section; a model has to invent it, and it will pick the default
MEDIUM no do and do not section; a model has to invent it, and it will pick the default
