Some whitespace in RSS feed of the blog are stripped

[brettcannon]

Describe the bug
If you look at the RSS feed for the blog you will notice whitespace is missing in various spots, leading to run-in words, no space after a comma, etc.

Expected behavior
To not have the missing whitespace.

To Reproduce
Look at https://blog.pypi.org/feed_rss_created.xml and notice e.g. "attacks,a", "domainand", "posture,making", and "namesto" for the first 2 paragraphs for https://blog.pypi.org/posts/2025-08-18-preventing-domain-resurrections/ .

My Platform

Additional context
This is not a new problem.

I believe this to be from the underlying library behavior of stripping spaces:
