## Key behaviours
- **On load**: cookie credentials restored → GET webhook fires → dropdown populated → scan input auto-focused
- **Enter key**: trims input → **duplicate check** → POSTs to webhook, prepends result row, clears + re-focuses input
- **Enter key**: trims input → duplicate check → clears input **immediately** → adds pending row → pushed onto FIFO queue → `drainQueue()` starts if idle
- **Clear button**: empties the table, clears the scan input, resets the scan counter
- **No user selected**: red toast + highlighted dropdown; does not submit
- **401 on any request**: modal prompts for credentials (pre-filled from cookie), saves to cookie, retries original call

- **Network error**: dismissing error banner; input selected so user can retry
- **Dropdown error state**: tapping/focusing the dropdown while it shows an error re-triggers `loadUsers()`
- **NDJSON/array/object**: `parseJson()` normalises all response formats from n8n
- **Duplicate scan**: `isDuplicate(code)` queries `.col-code` cells in the live table before every POST; if found, shows a warning toast and skips the webhook call entirely
- **Duplicate scan**: `isDuplicate(code)` queries `.col-code` cells (present on pending, resolved, and error rows) before enqueuing
- **Scan queue**: `scanQueue[]` is a FIFO array of `{ code, user, rowEl }`. `drainQueue()` runs sequentially in the background — one `processItem()` at a time. Scans can be added faster than the webhook responds; each gets its own pending row immediately
- **Pending row**: shows a spinner + `Processing… <code>` while the item is in-flight; replaced in-place by the resolved row or an error row
- **Error row**: red background, shows the error message and the raw code; code is still in `.col-code` so it cannot be re-scanned
- **Queue pill**: teal badge next to the scan counter showing `N pending`; hidden when queue is empty
- **Auth mid-queue**: if `processItem` gets 401, it returns `"auth"` to `drainQueue`, which pauses (`queueBusy = false`), shows the auth modal with `drainQueue` as the retry callback — queue resumes from the same item after login
- **Clear**: also drains `scanQueue` and resets `queueBusy`
## Scan flow (sequence)
```
Enter key
└─ enqueue(code)
├─ validation (user selected? duplicate?)
├─ scanInput.value = "" ← immediate clear
├─ addPendingRow(code) ← spinner row in table
└─ scanQueue.push(...) ← add to FIFO
└─ drainQueue() if idle
└─ processItem() loop
├─ fetch POST webhook
├─ resolveRow() ← replace spinner with result
└─ rowError() ← replace spinner with error
```
