Author: Dink Theory
Description: SEO-first pickleball blog theme. Implements the Dink Theory design system — four pillars (Rules, Courts, Gear, Drills), a card-grid homepage, a long-form article template, and an internal keyword-map page. Emits its own SEO metadata and JSON-LD, and steps aside automatically if an SEO plugin is active.
