/*!
 * sls-lang-widgets.css — styling for the Spanish/LOTE interaction widgets.
 *
 * Inherits the child theme's design tokens (--dark, --slate, --muted, --body-text,
 * --accent) with fallbacks, so it drops into the Nexus-variant theme without a
 * palette of its own. Nothing here is layout-critical: with the stylesheet absent
 * the widgets still render as legible, operable forms.
 *
 * Accessibility rules that are load-bearing, not decorative:
 *   - Correct/incorrect are never signalled by color alone; every state carries a
 *     text label and a left border weight change.
 *   - Focus rings are never removed. :focus-visible is thickened, not hidden.
 *   - Tap targets are >= 44px tall.
 *   - prefers-reduced-motion removes every transition and the shake animation.
