PROBLEM:
- apu-tables-auto-class.js was adding CSS classes to table rows after DOMContentLoaded
- This DOM manipulation caused CLS of 0.692 in Lab Data (PageSpeed Insights)
- body.wp-singular was the main culprit with 0.692 CLS contribution
SOLUTION:
- Added roi_add_apu_row_classes() function in Inc/apu-tables.php
- This applies the same logic server-side during the_content filter
- Classes (section-header, subtotal-row, total-row) are now in HTML from first render
- Disabled the JS script in Inc/enqueue-scripts.php
This should significantly reduce Lab Data CLS (target: < 0.1)
