Fix review feedback from PR #11

[TechNickAI]

Summary

Follow-up fixes from bot review comments on PR #11 (Add Anthropic emotion research to three pages).

• Fix AOS animation stagger: Video embed and first finding card both had data-aos-delay="100", causing simultaneous animation. Staggered cards to 200/300/400ms after video's 100ms.
• Add noreferrer to external links: Research paper link (anthropic page) and YouTube link (for-ai-models page) now use rel="noopener noreferrer" for privacy.
• Add referrerpolicy to iframes: Both YouTube embeds now include referrerpolicy="strict-origin-when-cross-origin".

cursor[bot]	Background alternation broken	Incorrect	Sections correctly alternate bg-of-surface ↔ bg-gradient-to-b

Test plan

• Verify emotion findings cards animate in sequence (video → card 1 → card 2 → card 3) on anthropic page
• Verify YouTube embeds still load correctly on both pages
• Spot check external links open correctly with noreferrer

Review of PR #12

This is a tidy, well-scoped follow-up that addresses the previous review feedback cleanly. All three changes are correct and intentional.

✅ AOS animation stagger fix (anthropic/index.html)

The fix is correct. The video embed uses data-aos-delay="100" and the three finding cards now use 200/300/400 — a clean 100ms cascade. The test plan covers this visually, which is appropriate since there's no automated way to assert animation timing.

✅ noreferrer additions (anthropic/index.html, for-ai-models/index.html)

Both external links correctly updated from rel="noopener" to rel="noopener noreferrer". This is the right change — noreferrer also implies noopener in modern browsers, so the single attribute would suffice, but keeping both is the conventional pattern and more explicit. No issue here.

✅ referrerpolicy on iframes (anthropic/index.html, heart-intelligence/index.html)

referrerpolicy="strict-origin-when-cross-origin" is appropriate for embedded YouTube iframes and matches the modern browser default, making the intent explicit. Consistent application across both embed instances is good.

Minor observations (non-blocking)

• The heart-intelligence/index.html iframe change only adds referrerpolicy — it's worth confirming the external link on that page (if any) already has noreferrer, but the diff doesn't show one needing it, so this appears complete.
• The triage table in the PR description is a helpful pattern — easy to audit what was and wasn't addressed.

Summary

All changes are correct, minimal, and well-justified. The PR description clearly traces each fix back to its source feedback. No concerns — this is ready to merge. 🙏
