/*
 * loading-spinner.css — BL-6: shared animated loading widget
 * registry: SCAFFOLD; cabling_task: BL-6; expires: 2026-07-18
 *
 * Namespace: .rfy-spinner*  (no overlap con .spinner globale legacy in globals.css).
 *
 * Anti-freeze: rotazione SEMPRE attiva tramite CSS keyframes locale,
 * fallback statico solo via @media (prefers-reduced-motion: reduce).
 *
 * Token usage:
 *   --color-primary    — colore arco rotante
 *   --color-border     — colore traccia statica
 *   --color-text       — colore label messaggio
 *   --color-text-muted — fallback label se --color-text non disponibile
 *
 * Dark mode: ereditato via [data-theme="dark"] sui token globali. Nessun
 * override hardcoded — l'unico hardcode è il fallback in .rfy-spinner--theme-dark
 * usato quando il consumer chiede esplicitamente tema dark forzato.
