{#- Chirp nav link macro — importable via {% from "chirp/nav.html" import nav_link %}

   Renders an <a> with hx-swap="innerHTML transition:true" for htmx-boost
   navigation. Use for links that perform full-page-style navigation
   inside #main. OOB swaps must not trigger transitions; only nav links do.

   Usage:
       {% from "chirp/nav.html" import nav_link %}
       {{ nav_link("/story/123", "Story title") }}
       {{ nav_link("/", "← Back", class="back") }}
-#}

{% def nav_link(href, text, class="", push_url=false) %}
<a href="{{ href }}"{{ class | attr("class") }} hx-swap="innerHTML transition:true"{{ ("true" if push_url else "") | attr("hx-push-url") }}>{{ text }}</a>
{% end %}
