🏮 Yardlight — dogfood page

This page embeds <masonbyte-yardlight> pointed at the local answer service. With a fresh checkout the service is inert: the widget renders, but answers arrive only after YARDLIGHT_ENABLED=true (start with YARDLIGHT_DRY_RUN=true) is set in the deployment environment.

This page is rollout step 4 in miniature: eventually the docs site renders here and the widget must answer its own documentation before any release ships to a product.
