Root cause: Tailwind arbitrary value z-[9999] was not in compiled CSS
(tailwind.css last modified Oct 9, feedback.js modified Nov 3).
Solution: Use inline styles with !important for all critical properties:
- position: fixed
- bottom/right positioning
- z-index: 999999
- display: flex
- visibility: visible
- opacity: 1
This bypasses Tailwind compilation issues and ensures button is visible.
