/* ============================================================
   Galleria fotografica e lightbox della pagina di dettaglio di
   una news - trascrizione di .gallery-section, .gallery-header,
   .gallery-desc, .gallery-year-tag, .gallery-grid,
   .gallery-item, .gallery-overlay, .lightbox e .lb-* di
   iniziative.css, piu' .video-grid dal blocco <style> di
   festa-malga-praino.html.

   Due differenze di markup, entrambe invisibili a schermo:

   - nel riferimento .gallery-overlay e' un <div> dentro un
     <button>, che non e' HTML valido (un pulsante accetta solo
     contenuto di frase): qui e' uno <span> con display: flex.
   - .lb-placeholder non c'e': nel riferimento il JS lo nasconde
     alla prima apertura e la lightbox parte nascosta, quindi
     non compare mai.
