Captcha Rush

Build a mobile portrait web app called “Captcha Rush”.

Cover: Giant flat color blocks slamming together to spell the title like a stamped poster. A full-bleed opening artwork drawn in code with the title integrated into it, then one short tutorial line and exactly one text button that starts play.
Core action (tap fast under a ten-second clock): Ten seconds per round, one absurd mini-captcha each: tap the exact word, pop the only real checkbox, catch the cat among dogs, tap the odd color — chain verifications until the clock beats you; overtime means bot.
Result: a reaction-humanity score with your streak count. Put a real Share button on the result screen (it must post to the Eazo community) and keep Replay next to it.
Visual bar: hard color slams between rounds, the timer bar burns down, streak numbers punch onto the screen.

Global requirements: mobile-first portrait, touch only, 100dvh with safe areas, no hover dependence. Built-in i18n with exactly two locales (English default, Chinese only after the user taps the EN/中文 toggle placed clear of the status bar), never mix languages on one screen, share output always English. Absolutely no external APIs, no login, no background music. Every control must actually work — no placeholders.
