/* IGWATCH Mini App — dark theme.
 *
 * One committed visual world instead of following the Telegram theme: a deep
 * violet-black ground with a violet-to-pink accent spent sparingly (figures,
 * the active tab, avatars). Colour lives in tokens only — no literal anywhere
 * below the token block.
 *
 * Layers, darkest to lightest: page -> card -> raised -> pressed. Nothing on a
 * dark ground needs a drop shadow to separate; a hairline and one step of
 * lightness do it better and never smear on an OLED panel.
