Thanks for this @gharneeyart! After checking, the content here is already on main — these exact pages (architecture.mdx, guides/fees.mdx, guides/networks.mdx, troubleshooting/passkeys.mdx) were merged via #284 and the follow-on docs PRs, and the content is byte-identical (I diffed troubleshooting/passkeys.mdx against main and it matches line-for-line). So this PR is a no-op against current main.

Could you go ahead and close this one? If you have additional docs improvements beyond what's already merged, a fresh branch off the latest main would be the way to bring those in. Appreciate the work!
