We should be consistent about the comment style. I prefer the use of one space after `#` and capitalize the first letter for full sentence comments. Same applies to similar comments in the changed lines.

The codebase has 883 occurrences of `#` immediately followed by a small letter:
`grep -o '#[a-z]' app/ -r | wc -l`
And 1056 occurrences of `#` followed by space and upper case letter:
`grep -o '# [A-Z]' app/ -r | wc -l`
