Why doesn't Nginx's location regular expression work correctly?

Question

Nginx

I prescribe
location ~ ^/(page)$
Example:
example.com/page - then page page will be displayed.
And if example.com/dsbfdbdfb - then 404.
That's right.
But if you put a dot at the end .
For example: example.com/page.
Then the page page will be displayed again, and in $requset_uri it will be just / page
How to avoid such garbage?

Remove brackets and dollar
