claude-design-system-prompt

4/5

This system prompt moves Tally to a cool grey-and-ink look with Bricolage Grotesque, Geist and a lime marker, and the dashboard is clean and well organized. One contrast bug on the closing CTA keeps it from a higher score.

styleseed

3/5

StyleSeed gives Tally a warm blush canvas, Plus Jakarta Sans and a deep green primary, with a full token set behind it. It's clean, with slight distance from the baseline, and the dashboard in Manrope matches. It was the longest run in the batch. Pick it if you want a design-system workflow more than a bold look.
