- Add GraphQL client fetching profile, stats, language aggregation, and per-repo commit histograms for the productive-time heatmap. - Render real SVG cards (profile details, top languages, stats grid, weekday×hour heatmap) with XML escaping and thousands-formatted numbers. - Expand theme palette to 30 built-ins ported from github-readme-stats; add -list-themes, multi-theme rendering, and 'all' shortcut. - Package as Docker-based GitHub Action (action.yml, Dockerfile, entrypoint.sh) with optional auto-commit of generated cards. - Release workflow publishes GHCR image and cross-platform binaries on v* tags. - Unit tests cover rendering, XML escape, number formatting, language sort.
