/* Funda Nami learner surface — plain but themed.
 *
 * Tokens are the owner's "Organic" design system (warm paper, terracotta,
 * olive; generous radii; pill controls; soft ink shadows), applied to a
 * deliberately plain functional shell that a later design pass restyles.
 *
 * The source system @imports Google Fonts (Caprasimo/Figtree). That import is
 * an EXTERNAL ORIGIN and is forbidden here (rulings P149/P150 — every byte
 * from our own origin; checks/ fails the publish otherwise), so the font
 * stacks below terminate in system-ui and no @import exists in this file.
 *
 * Accessibility floor for a pre-reader child: tap targets >= 64px, icons
 * beside every text affordance, focus-visible outlines kept.
