Summary

Brief description of changes:

Added the SEO/AEO layer to the generated README, without changing any code.

Added:
- Badges (npm version, npm downloads, license, TypeScript) using the correct package
  name @fastpix/fastpix-node
- A keyword-rich value paragraph naming concrete capabilities (uploads, live streaming,
  simulcasts, playback IDs, playlists, signing keys, video analytics, webhooks, in-video AI)
- A "Works with" line (Node.js 18+, TypeScript/JavaScript, ESM/CJS, npm/pnpm/yarn/bun)
  and docs / free-account CTAs
- An 11-question FAQ (install, auth, TS/ESM/CJS, upload, live stream, analytics, webhooks,
  errors, retries, custom HTTP client, tree-shaking, Node versions) - each linking a real section
- A "Which FastPix SDK should I use?" table linking the verified server SDKs
  (Node, PHP, Python, Go, Java, C#, Ruby) and the browser client repos

Structure:
- Demoted the second H1 (`# Development`) to `##` so there is a single page H1
- Added FAQ + the SDK table to the Table of Contents
- Kept the H1 ("FastPix Node.js SDK") so the TOC self-anchor keeps working

Every existing code block preserved byte-for-byte (18 blocks, 0 added); the generated
<!-- ... --> markers, <details> blocks, and developers' prose are untouched.

NOTE: this README is generated - apply via the generator template so it is not
overwritten on the next regeneration.

Code Examples (if Applicable)

N/A - no code examples were added or modified in this PR.
All existing code blocks were preserved exactly as-is (the developers' tested code),
verified byte-for-byte by hashing.

Testing

• All code examples tested — N/A (no code examples were added or changed)
• Links verified
• Grammar checked
• Formatting consistent

Review Checklist

• Content is accurate
• Code examples work — N/A (no code examples were added or changed; existing blocks preserved)
• Links are working
• Grammar is correct
• Formatting is consistent

SEO/AEO eval

Score: 7/8 Present; only the repo rename remains. About, Topics, and Website have been applied on the repo; this PR covers badges, landing structure, interlinks, and the FAQ. All correctness gates pass; developer code blocks unchanged (18/18 byte-for-byte, same hash, 0 added).

#	Criterion	Result
1	Repo name optimized	❌ node-sdk -> rename to fastpix-node (repo setting, not this PR)
2	About keywords	✅ applied on repo (keyword-rich)
3	Badges (npm, downloads, license, TypeScript)	✅ added in this PR
4	README descriptive (landing page)	✅ added in this PR
5	GitHub topics (16)	✅ applied on repo
6	Interlinks (verified 7-language SDK table + client repos + org)	✅ added in this PR
7	Releases + package	✅ 13 releases + 13 tags; published npm package @fastpix/fastpix-node (v2.0.9)
8	FAQ (11 questions)	✅ added in this PR

Gates: correct package name everywhere (@fastpix/fastpix-node), no code edited/added (18 blocks preserved, same hash), no fabricated repos (every SDK in the table verified live), license/version accurate (MIT, npm v2.0.9), links resolve.

Already applied on the repo (not part of this PR): About description, 16 Topics, and the Website field are live.

Still outstanding (repo settings / generator-side): rename node-sdk -> fastpix-node; add package.json description + keywords; add a LICENSE file. Because the README is generated, apply this PR's content via the generator template.
