Poem

🐰 A README polished, neat and spry,
A table of contents hops right by,
Old links turned local, tidy and bright,
Contribution steps laid out just right,
I nibble bugs and cuddle docs tonight! 🥕✨

In `@README.md`:
- Around line 11-20: Update the Table of Contents anchor fragments so they match
GitHub-generated heading slugs by removing leading emojis/punctuation and any
stray leading hyphens; replace entries like `#-who-should-use-this-repository`,
`#-guidance-for-contributors`, `#-guidance-for-mentors`,
`#-guidance-for-admins`, `#-guidance-for-ambassadors`, `#-document-index`,
`#-important-notes`, and `#-final-note` with the correct slugs such as
`#who-should-use-this-repository`, `#guidance-for-contributors`,
`#guidance-for-mentors`, `#guidance-for-admins`, `#guidance-for-ambassadors`,
`#document-index`, `#important-notes`, and `#final-note` so the links resolve on
GitHub.
