Rule page.viewport.missing
Declare a viewport meta
page.viewport.missing is a check in Crawlmind's site audit that grades medium-impact issues of this kind. This page explains why the rule matters and the exact fix.
Why it matters
Without the viewport meta, mobile browsers render the page at a desktop width and then shrink to fit: text is unreadable, tap targets too small. Google's mobile-first index downranks these pages explicitly.
The fix
```html
<meta name="viewport" content="width=device-width, initial-scale=1">
```
