how it works: - hx-indicator adds the htmx-request class to the target of choice - with tailwind, we can use `group-[.class]` to check if a parent element has a certain class, and style things conditionally - by applying `group-[.htmx-request]`, we can detect when a request is in progress, and show/hide a lucide loader - the loader is a static icon made to spin using the `animate-spin` class
