## Summary
Reframes the browser's native pull-to-refresh on touch devices as a
**WebSocket reconnect** instead of a full page reload. On data pages
(Packets, Nodes, Channels — and globally, since the WS is shared) a
downward pull at `scrollTop=0` cycles the WS, which is what users
actually want when they reach for that gesture.
Fixes#1063.
## Behavior
- **Touch-only**: gated by `('ontouchstart' in window) ||
navigator.maxTouchPoints > 0`. Desktop is untouched.
- **Scroll-safe**: every handler re-checks `scrollTop > 0` and bails out
— never hijacks normal scroll.
- **Visual affordance**: a fixed chip slides down from the top with a
rotating ⟳ icon; opacity and rotation scale with pull progress (0 →
`PULL_THRESHOLD_PX = 80px`).
- **`preventDefault` is conservative**: only after `dy > 16px` and only
on `touchmove`, so taps and short swipes are not affected.
- **Result feedback**: a brief toast — green `Connected ✓` if WS was
already OPEN, `Reconnecting…` otherwise. Both auto-dismiss after ~1.8s.
- **Reconnect path**: closes the existing WS so the existing `onclose`
auto-reconnect fires immediately; an explicit `connectWS()` is also
called as a safety net when `ws` is null.
- **No regression** to existing WS auto-reconnect — same `connectWS` /
`setTimeout(connectWS, 3000)` chain, just kicked manually.
## TDD
- **Red commit** `f90f5e9` — adds `test-pull-to-reconnect.js` with 6
assertions; stub functions added to `app.js` so tests reach assertion
failures (not ReferenceError). 3/6 fail on behavior.
- **Green commit** `53adbd9` — full implementation; 6/6 pass.
## Files
- `public/app.js` — `pullReconnect()`, `setupPullToReconnect()`,
`_ensurePullIndicator()`, `_showPullToast()`, `_isTouchDevice()`. Wired
into `DOMContentLoaded` next to `connectWS()`. Touched the WS section
only.
- `test-pull-to-reconnect.js` — vm sandbox suite covering exposure,
WS-close, listener wiring, threshold trigger, scroll-position gate.
## Acceptance criteria check
- ✅ Pull-down at scroll-top triggers WS reconnect + data refetch
(debounced cache invalidate fires on next WS message)
- ✅ Visible affordance during pull (rotating chip)
- ✅ Resolves on success (toast), shows status toast on disconnect path
- ✅ Disabled when not at `scrollTop=0`
- ✅ No regression to existing WS auto-reconnect
