/* ==========================================================================
   piese cântare — piese-cantare.css · UI kit v1.0
   Tokens + components for the storefront and the compact admin extension.
   - Everything is scoped under .mt-root and prefixed mt-.
   - Responsive rules are container queries on .mt-root (name: mt).
     They map 1:1 to @media (max-width: …) if the site prefers media queries.
   - State helper classes (.is-hover, .is-focus, .is-active …) mirror the
     real pseudo-classes so states can be rendered statically.
