/*
 * Hello Budget Mini App — GPM design system.
 *
 * Slate ink, one cyan accent used sparingly, Geist everywhere with Geist Mono for
 * labels and amounts, borders instead of shadows. The dark palette is not an
 * afterthought: most people read Telegram in dark mode.
 *
 * Every rule is written once. Half of this file used to be here twice — the keypad, the buttons,
 * the fields, the empty state — with the second copy quietly winning, so reading the first one
 * told you the wrong thing about what the screen looked like.
