Hallmark
The design skill that ends AI slop, in Claude Code, Codex and OpenCode.
Hallmark v2 designs before it codes. It deals one of forty-eight themes, builds with real photographs, then checks its own work for the habits that make a page look generated.
I designed v2 with Hassan: the rules, the themes, the linter and the new site. Every page below is one Hallmark made from a one-line brief, left as it made it.
14 sites from 14 one-line briefs, made by Hallmark and left as it made them. Point at one to read it top to bottom.
