Bouncy Button
fun BouncyButton(text: String, onClick: () -> Unit, modifier: Modifier = Modifier, color: Color = LocalPalette.current.accent, glyph: Glyph? = null, enabled: Boolean = true, compact: Boolean = false)
Slim pill button. A solid color gets a gradient face and a coloured glow beneath; a translucent colour (e.g. palette.surfaceHi) renders as glass.
