Prism Latin

Build a mobile portrait web app called “Prism Latin”.

Cover: A 6×6 stained-glass Sudoku that replaces digits with six colors and resolves into a shareable animated color composition. The title sits on a clean band with a one-line tagline, a two-line how-to-play block with small icons, and a single Enter button.
Core action (Tap the outlined pane, then choose its missing color): Choose an empty glass pane. Use each of six colors once per row, column and box.
Result: an English completion card — “Your logic window is complete.” — with time, moves and a miniature board. Put a real Share button on the result screen (it must post to the Eazo community) and keep Replay next to it.
Visual bar: Complete a stained-glass logic bloom.

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.
