+/**
+ * Handles Astro Action requests in both modes:
+ *
+ * - **RPC**: POST requests to `/_actions/<name>` (originating from the
+ *   generated JS client). Runs the action and returns the serialized result
+ *   as the response, so the caller can short-circuit rendering.
+ * - **Form**: POST requests with `?_action=<name>` targeting a page route
+ *   (originating from an HTML `<form action={actions.foo}>`). Runs the
+ *   action, stashes the result into `locals._actionPayload`, and returns
+ *   `undefined` so the caller continues to render the page.
+ *
+ * Non-action requests are a no-op (`undefined`).
+ *
+ * This handler is invoked at the bottom of the middleware chain, before
+ * page dispatch. That placement preserves the existing behavior where
+ * user middleware sees action requests and response finalization (cookies,
+ * sessions, etc.) runs around the action response.
