Pick a Number

Choose a number between one and ninety-nine. It must be even, its digits must sum to a prime, it must not be anything you already tried — and the demands keep arriving.

Build a mobile portrait web app called “Pick a Number”.

Cover: A watercolour field of floating numbers, the title bled into the wash behind them. 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 a number in the grid): Tap a number from a grid of ninety-nine; each accepted pick adds one more condition, and the grid live-dims every number that the accumulated conditions now forbid.
Result: a fate card with your final number, conditions survived and the number's reading of you. Put a real Share button on the result screen (it must post to the Eazo community) and keep Replay next to it.
Visual bar: watercolour blooms spreading from the tapped number, forbidden numbers fading into the paper, ripple rings on rejection.

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.
