- Replace btn/btn-secondary on CTA buttons with cta-btn/cta-btn-outline
(isolated from global .btn-secondary { color: #144784 !important } cascade)
- Rename author-bio inner classes (author-info -> bio-info, etc.) to prevent
collision with article inline <style> .author-info definitions
- Both issues were CSS class name conflicts, not specificity bugs
- Rewrite meta descriptions on 4 high-impression articles (churn, compliance, data quality, ecommerce)
- Fix data-quality-validation-pipelines title & description to capture zero-click statistical validation queries
- Add FAQPage schema to churn prediction and data quality articles
- Add service CTA box to article-footer.php (appears on all blog articles)
- Add responsive CSS for CTA box in main.css
