Redraw the inline card-into-reader SVG after sim.svg: a rounded card
with the top-right cut corner and the 3x2 contact pad, sliding behind
the reader bar. The viewBox grew to 72x48 and the resting position is
0, so the card is no longer clipped at the top; the insert slide is
20px. The currentColor/Tailwind theming and the reduced-motion
fallback are unchanged.

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).
