   1. Industry sub-pages (.ind-section) had no bg → content invisible

   2. Stat counter numbers wrapped in <em> → became serif italic, looked
      weak vs bold display intent
   3. Hero too bare on cream after hero__bg hidden
   4. Stack-diagram cards too low contrast on cream bg
   5. Stack diagram + layers grid borders too faint
   6. Quick-nav → footer sharp transition
   7. Footer logo lost visibility (white logo on dark footer is OK,
      but the prior cream-mode invert filter shouldn't apply in <footer>)
