/*
 * Odolim — site vitrine.
 *
 * The palette is the app's own: #0E1A30 is its splash background, #16233F and
 * #0A1122 the two stops of its icon gradient. Green and red are verdicts, never
 * decoration, and both are darkened from the app's iOS-derived values because
 * #1E8E3E only reaches 3.7:1 on this ground — short of AA.
 *
 * One raised surface (the instrument panel), one movement (the odometer drums).
 * Everything else sits on the ground, separated by hairlines.
