/*
 * AMOSHA UI Foundations v0.1
 *
 * Preview layer loaded after existing legacy CSS.
 * Purpose:
 * - centralize brand/semantic tokens without destructive rewrites;
 * - preview Midnight/Sapphire dark mode;
 * - introduce Muted Gold as a rare value accent;
 * - normalize focus, motion and selection behavior.
 *
 * Do not add component-specific hacks here. Move stable rules into the
 * owning component stylesheet once a migration is verified.
