Defined in:

Overview

Coordinates hot reloading of site code and content during development.

The ReloadCoordinator watches the site code and content directories for changes using the Listen gem. When files change, it marks the appropriate component as dirty and reloads it on the next request.

It uses a read-write lock to ensure thread-safe reloading while allowing concurrent reads during page rendering.
