- pyproject.toml urls: Homepage + Documentation → new domain
- README badge row + sdist exclude comment
- docs-site .env.example + astro.config.mjs site URL + DEV_DOMAIN default
- Version bumped to 2026.05.08.1 (PEP 440 post-release; PyPI 2026.5.8
still resolvable but with stale URL — yank or leave per preference)
