/* Viper Wave: the launch page.
 *
 * One theme, dark, because the game is dark-only (project.yml: UIUserInterfaceStyle Dark).
 * Colours are the Vice Sunset theme's (Resources/Themes/vice-sunset/theme.json); the
 * hero's sky, layers and reveal follow the approved splash (Martin's "Viper Wave
 * Approved" pack, 07 Source/Splash.tsx). One accent: the theme's "button" gradient,
 * pink to orange. Shapes: buttons are pills, media frames are 24px, nothing else rounds.
