Starting point for any Drupal 11 module, theme, or full site intended to live contrib-grade from day one. Ships the cross-cutting foundation — DDEV stack, composer baseline, autoload conventions, docs/decision-log scaffold — so the next project earns the wins of the last. PSR-4 module + Olivero subtheme scaffolding included.
Distilled from the Drupal three.js theme project; retrofits from real projects propagate back here per the skeleton-as-living-doc protocol.
