Loading States

Import @wrux/astro-datastar/loading.css once, then:

• data-indicator="_loading" on the element that initiates the request — it sets the signal to true while a request is in flight. (On a form-submit action, that’s the <form>, not the button.)
• ds-busy-fade + data-attr:aria-busy on the region the response replaces — it fades and ignores pointer events while busy.

<input data-bind:q
       data-on:input__debounce.300ms="@get('/api/search')"
       data-indicator="_searching" />

<div class="ds-busy-fade"
     data-attr:aria-busy="$_searching ? 'true' : 'false'">
  <ul id="results">…</ul>
</div>

See it live on active search and the form (button label swap + fade).
