GitHub-style contribution calendar with compound calendar, block, total-count, and legend parts — pass raw Activity data or just a GitHub username and it fetches and caches the last year of contributions itself, shimmers a skeleton grid while loading, then fades the muted grid in and lights the greens up level by level — lightest to darkest — with springy pops, plus custom per-day tooltips and reduced-motion aware behavior.
