I really like the changes introduced in this pull request, all the changes are very well-written!

I noticed a few typos and thought I'd gather them as a review.

Thank you for taking the time to make all those changes! It looks like you didn't "build" the security.txt file to get all the other file formats to have the same changes... I'm not familiar with the process but thought I'd point it out, just in case.

After your latest changes, I only found one typo. Everything looks great otherwise!

Should be fixed now

To regenerate the draft I usually run "make clean txt html"
