Fix: Update dropout rate for consistency with retention metrics

[donbr]

Summary

Updates dropout rate from <5% to <10% to align with the 90%+ retention rate mentioned throughout the site.

Problem

The site mentions "90%+ retention rate" but also claimed "<5% dropout rate" which would imply 95%+ retention. This inconsistency needed to be resolved.

Solution

Updated both occurrences of "<5% dropout rate" to "<10% dropout rate" to maintain consistency:

• 90% retention = 10% dropout ✓
• Still an impressive achievement (vs. 20-30% industry average)

Changes

Updated in src/pages/HomePage.tsx:

1. Line 91 - The Journey section: "Teaching 100+ engineers... with a <10% dropout rate"
2. Line 284 - Teaching & Mentorship section: "Consistently Lowest Dropout Rate: <10%"

Test Plan

• Build succeeds without warnings
• Text updates correctly displayed
• Messaging now consistent across all metrics

This ensures all teaching impact metrics are aligned and accurate.

Code Quality & Best Practices

Strengths:

1. Mathematically Correct: The change properly aligns the dropout rate with the stated 90%+ retention rate

   • 90% retention = 10% dropout
   • Fixes the previous inconsistency where <5% dropout would imply 95%+ retention

2. Consistent Application: Both occurrences updated correctly:

   • Line 91 (The Journey section)
   • Line 284 (Teaching & Mentorship section)

3. Proper HTML Encoding: Uses < for the less-than symbol, maintaining correct HTML entity usage

4. Minimal, Focused Change: Only touches what's necessary (2 additions, 2 deletions)

5. Well-Documented PR: Clear summary, problem statement, and test plan in PR description

---

Verification of Consistency

I verified all mentions of retention/dropout metrics across the codebase:

• Line 33: "90%+ student retention rate" (quote in hero)
• Lines 68-69: "90%+" retention metric badge
• Line 91: "<10% dropout rate" (updated)
• Line 284: "<10% dropout rate" (updated)

All metrics are now mathematically aligned and consistent across the entire page.

Testing & Build

The PR description indicates:

• Build succeeds without warnings
• Text updates correctly displayed
• Messaging now consistent across all metrics

Recommendation: Consider verifying the build succeeds by running npm run build

Performance Considerations

No Performance Impact: This is a text-only change with zero performance implications.

---

Security Concerns

No Security Issues:

• Proper HTML entity encoding maintained
• No XSS vulnerabilities introduced
• No external dependencies added

---

Potential Improvements (Optional)

While not required for this PR, consider these enhancements for the future:

1. Constants for Metrics: Extract retention/dropout rates into constants to prevent future inconsistencies
2. Automated Validation: Add a simple test to ensure dropout + retention = 100%
3. Typography Component: Consider using a reusable component for metric displays to ensure consistency

Summary

Verdict: Ready to Merge

This PR successfully:

• Fixes a mathematical inconsistency
• Maintains code quality standards
• Applies changes consistently
• Follows proper HTML encoding practices
• Includes clear documentation

The change is accurate, well-scoped, and ready for production. Great attention to detail in catching this inconsistency!
