/* AiB Platform — upload: the drop zone and the file queue under it.
   The zone is a <label> around a real file input, so a click, a tap,
   Enter/Space on the focused input and a no-JS form post all work; the
   runtime adds drag-and-drop (.is-over while a file hovers it). The queue
   lists what was picked, each row with a status dot and the same status
   in words. */
