The prompt

Create a contribution rhythm card with Tailwind CSS. Include a twelve-week calendar heatmap, weekday labels, low-to-high legend, current streak, active days, strongest weekday, and a short interpretation. Add JavaScript that renders deterministic daily values into the grid, gives each cell an accessible date-and-count label, and filters the calendar between commits, reviews, and deployments.

Paste it into Claude, Cursor, v0 or any AI coding tool. Prefer the finished markup? Open the Tailwind source.
