- Track scroll position per log pane (container logs, build logs, deployment cards)
- Auto-scroll to bottom only when user is already at bottom (tail-follow)
- When user scrolls up to review earlier output, pause auto-scroll
- Show a '↓ Follow' button when auto-scroll is paused; clicking resumes
- Only scroll on actual content changes (skip no-op updates)
- Use overflow-y: auto for proper scrollable containers
- Add break-words to prevent horizontal overflow on long lines
