A tiny, calming one-gesture toy: press and hold the cup to sip. The tea drains, bubbles rise, the cup wobbles, and boba pearls detach from the pile one by one, fly to the mouth of the straw and ride up it — steadily, the whole time you are drinking, not just at the end. Empty the cup and you get the hollow last slurp and an "All gone!" A running total of every cup you have ever finished sits above the drink and carries over the next time you come back. Pure CSS and DOM with a WebAudio slurp — no images, no libraries, no audio files. Works in light and dark, and respects reduced-motion.
