/* styles.css — Butterfly Keys.
 *
 * A garden, drawn with CSS and SVG only. No web fonts (the CSP would block a
 * third-party one and vendoring a display face is not worth the bytes), so the
 * type is a system stack — but sized enormously, which matters far more to a
 * six-year-old than the typeface does.
 *
 * Three rules shape the whole sheet:
 *
 *   1. **The keyboard is the app.** It is sized from one unit, `--u`, derived
 *      from the width of its own container (with a viewport-height ceiling so a
 *      short laptop screen never needs scrolling). Every key is exactly `--u`
 *      square, so all thirty caps match no matter how many keys a row holds,
 *      and the board grows to fill a 1600px window instead of sitting in a
 *      1000px box. On a 1280x800 laptop a key lands around 88px.
 *   2. **Nothing red, nowhere.** The "nudge" state is a wiggle and the key's own
 *      hue. There is no cross, no stop colour and no failure styling anywhere.
 *   3. **Everything the child touches is huge.** No interactive target is under
 *      44px and most are two or three times that.
