// Docs information architecture, organized by the Diátaxis framework:
//   tutorials    — learning-oriented, start-to-finish lessons
//   how-to       — task-oriented, goal-focused recipes
//   reference    — information-oriented, dry technical facts
//   explanation  — understanding-oriented, background & rationale
//
// This registry is the single source of truth for the docs nav, the
// static-param generation, and the content pipeline. Each page's body lives at
// content/docs/<category>/<slug>.md and is rendered by <DocsMarkdown>.
