/* Offrivals — landing page
 *
 * Tokens first, then base, then components in page order. No build step: this
 * file is served as is. The palette and type come from the Offrivals brand
 * manual: Carvão and Papel as the base, Rosa-líder as the only accent, one
 * family (Archivo) in two widths, 125 for display and 100 for text. The page
 * keeps the black-canvas, pill vocabulary of fora.so.
 *
 * Rosa-líder is a signal, not an interface colour: it marks the symbol, the
 * value in play and whoever receives it. There is no green and no gold, and
 * failure is never red: on the scoreboard, state is a shape (full disc kept,
 * empty ring slipped, dashed ring no proof) plus grey text with the amount.
