Use when the maintainer asks to build or upgrade a Feynman-style HTML study or teaching page in the job-search / AI-native learning workspace: "flesh out / punch up / make a learning page", turning dense notes or a markdown study pack into real teaching material, adding diagrams, charts, icons, or inline SVG to a study or reference page, making a guide "top notch" or "ace-interviews" ready, building interview-prep or onboarding HTML, creating a themed standalone HTML page that must match the dark "mission-control" dashboard identity, or "do the same to the rest of the library".
