Route definitions with string-based loaders/actions\n\n```ts\nexport const routes = defineRoutes([\n {\n path: \"/\",\n Component: App,\n action: \"./routes/Topics.action.ts\", // server-only, never shipped to client\n children: [\n { index: true, Component: Home, loader: \"./routes/Home.loader.ts\" },\n { path: \"topics/:topicId\", Component: Topic, loader: \"...\", action: \"...\" },\n ],\n },\n]);\n```\n\nLoaders and actions are specified as **relative file paths** — the server dynamically imports them, while the client only gets lightweight stubs.\n\n### 2. Loader pattern — export a named `loader` function\n\n```ts\n// Home.loader.ts\nexport async function loader() {\n return { topics: await getAllTopics() };\n}\n```\n\n### 3.
