   Lights Out Neon — guscio comune del sito
   ===========================================================================
   Stessa impalcatura di Pocket Games (barra alta con lingua, blocchi a due
   colonne, footer, testo lungo), con l'aspetto dell'app: notte blu-viola,
   celle spente grafite, luce ciano che brilla. Il gioco (/play) non passa di
   qui. Le regole di una sola pagina restano nel <style> della pagina.
