Note

Low Risk
Documentation-only edits (wording, structure, links) with no product or runtime code changes; main risk is minor inaccuracies or broken links.

Overview
Improves the integrate-sns.mdx tutorial by rewriting the intro to better explain Embedded Wallets (SSS/MPC) + SNS value, and clarifying the onboarding/domain-management goals.

Restructures headings from a generic “Steps” section into explicit Step 1–4 sections, adds callouts (:::tip, :::note) for dependency explanations and dashboard guidance, and updates links (notably RPC configuration).

Refreshes the ending content by removing the “Conclusion” section, tightening “Testing and best practices” formatting, and replacing it with a Next steps section with updated resource links.
