+Core Architecture
+
+  server.re - Main entry point:
+  - Uses Dream web framework (OCaml's web server)
+  - Sets up routing with getAndPost helper for progressive enhancement
+  - Serves static assets (CSS, JS) and handles React rendering
+
+  Key Libraries (from dune file):
+
+  - dream - Web framework
+  - react/reactDOM - Native React implementation
+  - demo_shared_native - Shared components
+  - lwt.unix - Async I/O
+  - yojson - JSON handling
+
+  Rendering Pipeline
+
+  Three rendering modes:
+  1. renderToString - Basic SSR (line 28-31)
+  2. renderToStaticMarkup - No hydration attributes (line 34-38)
+  3. renderToStream - Streaming SSR with React Server Components
+
+  React Server Components (RSC)
+
+  DreamRSC.re handles the magic:
+
+  Content negotiation:
+  switch (Dream.header(request, "Accept")) {
+  | Some(accept) when is_react_component_header(accept) =>
+    stream_model(~location=Dream.target(request), app)  (* RSC payload *)
+  | _ =>
+    stream_html(~bootstrapScripts, app)  (* Full HTML *)
+
+  Server Actions (lines 50-87):
+  - Reads ACTION_ID header
+  - Decodes form data or request body
+  - Calls registered server function via FunctionReferences.get
+  - Streams response back as application/react.action
+
+  Request Flow
+
+  1. Client request → Dream router
+  2. Accept header check → RSC payload vs HTML
+  3. Server function lookup → FunctionReferences registry
+  4. Component rendering → ReactServerDOM.render_model/render_html
+  5. Streaming response → Chunks sent via Dream.write
+
+  File Structure in OCaml syntax:
+
+  (* Main server setup *)
+  let server =
+    Dream.logger (
+      Dream.router [
+        get_and_post "/" Pages.Home.handler;
+        Dream.get "/static/**" (Dream.static "./build/client");
+        (* ... more routes *)
+      ]
+    )
+
+  (* Page handler example *)
+  let handler _request =
+    let app = Document.make [
+      Html.h1 [React.string "Hello"]
+    ] in
+    Dream.html (ReactDOM.renderToStaticMarkup app)
+
+  The beauty is it's a standard Dream web server that happens to render React components natively, with RSC streaming as an enhancement
+  layer on top!
