/*
 * BikeGuess. Dark ground, one accent — and the accent is BikeFind's own yellow, so the game reads
 * as the shop's sibling without looking like the shop (design canvas, 2026-09-20). The ground stays
 * dark on purpose: nobody mistakes a game for a recommendation. Mobile first: one column, 16px
 * gutters, every tap target at least 48px, the price in a size a thumb can read from arm's length.
 *
 * `--mid` is amber, not yellow: the middle tile, the "close" reaction and the accuracy pill share
 * it, and they must not be mistaken for the brand colour beside them.
