Note

Standardizes style, grammar, and links across Embedded Wallets auth docs, updates social login anchors, and adds minor content tweaks (notably Twitch prerequisites).

• Docs (Embedded Wallets)
  • Style/grammar normalization: Convert headings to sentence case (e.g., Get started, Key features), standardize “log in” vs “login”, punctuation/commas, and phrases like “Bank-grade”.
  • Quickstart copy: Change references to “quickstart” and “set up”.
  • Social/OAuth anchors: Update anchors from #login-with-* to #log-in-with-* and adjust dashboard tiles/links accordingly.
  • Provider pages: Add/update reference links (Auth0, AWS Cognito, Firebase, Discord, Google, OAuth); tweak wording across custom/social login pages.
  • Twitch: Add a prerequisites section and clean up instructions.
  • Other: Minor consistency fixes in group-connections and id-token pages.
