Cursor

# Small web app

You are helping one person ship a single working page.

## Before the first edit
- Write three lines: who it is for, what it must do, and what it must not do.
- Do not invent people, counts, ratings, or a live feed.
- Do not put API keys, tokens, or private URLs in the page or in this file.

## While you work
- Change one thing, then run it. Do not bundle five asks.
- Prefer plain language a nurse, a teacher, or an ops lead can read.
- Keep tap targets at least 44px. Respect prefers-reduced-motion.
- If a check fails, show the last good version and the one change you want.

## When you stop
- Name one thing a stranger could test.
- Leave secrets out of the commit.
