/* Likelihood design system: tokens, base type, primitives (buttons, segmented control, inputs, chips, tags),
   app chrome (header, nav, footer, modal, toasts) and skeletons. Screens live in launchpad.css.

   Type: the system stack (SF on Apple platforms), scale 34/28/22/17/15/13/11, tabular figures everywhere,
   600/700 headings and 400/500 body, -0.02em on large headings. Neutral greys, one accent, green = buy, red = sell.
   Spacing 4/8/12/16/24/32. Radii 10 (inputs, small), 16 (cards, buttons), 20 (panels, modal), pill for chips.
   Light palette on bare :root; dark from the OS unless the viewer picked light; an explicit dark pick wins too. */
