- Tabs now scroll horizontally (overflow-x: auto) with hidden scrollbar
- Each tab maintains its natural width (flex-shrink: 0) — no wrapping
- Label stays pinned (flex-shrink: 0) so it doesn't get lost when scrolling
- Fix auth middleware: make GET /api/agents public so agent profiles
load in Firefox mobile (browser doesn't send Basic Auth on XHR)
- Fix CSS: use display: grid; justify-items: center on .content
instead of margin: 0 auto on .panel — Firefox fails to honor
margin: auto with percentage width inside flex containers
- Add box-sizing: border-box to panel elements
- Bump cache busters (v=13 for CSS, v=2 for JS)
Root cause: Firefox mobile on Pixel 4a rendered .panel with
width:72%; margin:0 auto shifted 242px right (flush to edge).
CSS Grid centering resolves the cross-browser rendering difference.
