The waiting phase is the only moment the operator must act, so it now:
- shows a card-into-reader SVG animation in the status modal (inline
SVG, CSS keyframes in src/style.css; reduced-motion users get the
static card-above-the-slot picture);
- plays a short Web Audio chime once per card, edge-triggered in the
2 s poll so it never repeats (the AudioContext is unlocked by the
Start click);
- sets the tab title to "Insert next card" while the window is hidden;
- offers a speaker toggle next to the status (persisted as
simple_ram_batch_sound, on by default).
The prebuilt style.css was rebuilt: it had gone stale and lacked
utilities the UI already used (bg-blue-50 on the batch notice,
inline-flex, mx-2, max-h-48, w-44, min-w-24).
