Root cause of the recurring nav-vanishing family of bugs — confirmed
live via operator console probe at vw=1030 on /#/channels (also
reproduces on /#/home, /#/packets, all routes).
## Symptoms
1. All `.nav-links` (Home, Packets, Map, Live, Channels, Nodes) and
brand + More button render OFFSCREEN above the visible top-nav band.
`.nav-left` reports y=0..52 but every child reports y=-47.5.
2. More dropdown when opened shows only ONE item ("Tools") instead of
the 6 expected (Channels, Tools, Observers, Analytics, Perf, Audio Lab).
## Root cause
`.nav-left { overflow: hidden }` at `public/style.css:509`. With flex
children whose effective layout exceeds the container box, Firefox clips
children to negative y. The same `overflow: hidden` ALSO clips the
descendant `.nav-more-menu` dropdown contents.
## Fix
Drop `overflow: hidden` from `.nav-left`. The original
horizontal-overflow guard from #1066 is preserved at the `.top-nav`
level (which still has `overflow: hidden`).
## Verification
Operator console probe after applying the same `overflow: visible`
in-page:
- All 6 visible nav links render at y >= 0 inside the top-nav.
- More dropdown contains all 6 expected items (Channels, Tools,
Observers, Analytics, Perf, Lab).
- Both bugs collapse into ONE root cause.
## Why prior fixes didn't catch this
- #1400 fixed `.nav-link { min-height: 48px }` overflow — reduced
children from 56px to 47px tall. Helped slightly but didn't address the
`.nav-left { overflow: hidden }` interaction.
- #1391, #1394 fixed the active-pill-in-overflow algorithm. Different
layer.
- #1311, #1148, #1106, #1102, #1097, #1067, #1055 — every prior
Priority+ fix treated overflow as an algorithmic question, never as a
CSS clipping bug at the container level.
22nd nav fix in this saga. This one targets the actual cause.
