Sign Here

A signature that has to obey: one unbroken stroke, exactly three closed loops, never leave the box, cross the centre line twice. Draw it again and again until the notary is happy.

Build a mobile portrait web app called “Sign Here”.

Opening: no cover screen — the app opens straight into the live interactive scene (an official signature box on cream paper with a fountain-pen nib waiting at the left edge); the title lives inside the scene and any hint dissolves on the first touch.
Core action (draw with one finger inside the box): Draw a signature inside a box while one clause at a time is enforced — one stroke, loop count, staying inside, crossing the centre, minimum length — and the ink is judged geometrically the instant you lift.
Result: a notarised signature card with your final signature, clauses met and a forgery-resistance score. Put a real Share button on the result screen (it must post to the Eazo community) and keep Replay next to it.
Visual bar: ink thickness following speed, loops highlighted as they close, the box flashing on an escape, wax seal on approval.

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.
