 * Two families and one accent, deliberately.
 *
 * Everything structural is neutral; the accent is spent only on the number
 * the product sells (what a turn did not cost) and on the SKU it chose. If
 * the accent shows up anywhere a reader is not meant to look, it stops
 * meaning anything.
 *
 * Mono is not decoration either. It is for figures, SKU names and the prompt
 * itself - anything the reader is meant to compare digit by digit or type
 * into. Prose stays in the sans.
 *
 * Ported from the reference app's styles.css + the StyleX classes its
 * components carried, with the same class names the Go templates use.
