In `@README.md`:
- Line 7: Replace the misspelled word "dominiant" with "dominant" in the README
where the sentence starts "There are two dominiant _representation_ systems in
defi today:" so the user-facing line reads "There are two dominant
_representation_ systems in defi today:"; update only that token to correct the
spelling.
- Around line 9-10: Fix the two typos in the README.md line starting with
"Fungible tokens: Ideal for trading..." by replacing "interoperatiblity" with
"interoperability" and "transerring" with "transferring" so the user-facing
description reads correctly.
