/* ────────────────────────────────────────────────────────────
   base.css — Terra Mia Hugo Theme — neutral foundation
   Aggiornato 2026-05-15 (post-blueprint refactor)

   Cosa contiene:
   - Reset minimo (box-sizing, margin/padding root)
   - Body defaults (font-family fallback, smoothing, color scheme dark)
   - Scroll behavior + skip-link a11y
   - Container utility (.tm-shell)
   - Scroll-reveal IntersectionObserver styles ([data-reveal])
   - Touch target minimum a11y

   Cosa NON contiene:
   - Palette colori (sta in dna-*.css, custom properties)
   - Tipografia specifica DNA (font-family, sizes — sta in dna-*.css)
   - Sezioni specifiche (hero/cards/etc — sta in dna-*.css)

   Caricato SEMPRE in baseof.html, prima di qualsiasi DNA css.
