Add one plugin to modern.config.ts. Types regenerate automatically on every route change, in dev and build.

Dynamic [id], optional [id$], splat $, pathless __layouts, flat a.b.c segments, config routes and multi-entry apps — derived from Modern.js's own route parser, not a re-implementation.

Ships typed Link, Navigate and useNavigate wrappers. Paramless routes accept a plain string; routes with params require them — autocompleted and typechecked.

Generates a single .d.ts file — declaration merging does the rest. Nothing is added to your bundle beyond tiny static wrappers.

npx modern typegen generates types without a dev server, so `typegen && tsc --noEmit` catches broken links in CI.

Full re-export of @modern-js/runtime/router, originalNavigate for raw navigation, and a RoutePathname union for your own APIs.
