Name: Random number generator
Specification:

Random Number Generator — Product Requirements Document

Overview

A minimal, single-purpose random number generator that produces a random integer between 1 and 100 each time the user taps a Generate button. Clean interface, no history, no settings, no extra features.

Core Features

• Number display — Shows the most recently generated number in large, prominent text centered on screen.
• Generate button — A single tap generates a new random integer between 1 and 100.
• Result animation — The displayed number animates briefly (e.g., a smooth scale or flip transition) when a new number appears, making the result feel responsive and satisfying.

Content

• No instructional text, labels, or explanation beyond the number itself and the button.
• The button should clearly convey its action — text like "Generate" or a recognizable icon (e.g., dice or shuffle symbol).

Visual Style

• Clean and minimal — plenty of whitespace, no clutter.
• High contrast between the number text and the background for easy readability at a glance.
• The generate button should be prominent, easy to tap, and centered below the number.
• Optional: a subtle background color or gradient that stays calm and not distracting.

The specification above is final and approved. Implement the app now in code. Do not ask for confirmation, do not summarize what you will build, do not ask follow-up questions.

CRITICAL: Do not modify, remove, or bypass the Pi Network SDK and authentication integration that ships with this template. The app must always initialize the Pi SDK and authenticate the user via Pi on startup. Do not add code that disables, mocks, or skips Pi authentication.
