+# Static Files Directory
+
+This directory is for serving static files (CSS, JavaScript, images) through FastAPI.
+
+Currently, all CSS and JavaScript is embedded directly in the HTML template for simplicity.
+
+You can add files here if you want to separate them:
+- `css/` - Stylesheets
+- `js/` - JavaScript files
+- `images/` - Images and icons
+- `fonts/` - Custom fonts
+
+Files will be accessible at `http://localhost:5000/static/<filename>`
