/**
 * Widget QR della dashboard
 *
 * Stava dentro dashboard.php, in un blocco <style> in mezzo al markup.
 * Riguarda un pezzo solo: il riquadro che genera e mostra il QR.
 *
 * SI CARICA NELLO STESSO IDENTICO PUNTO in cui stava il blocco. Non e' un
 * dettaglio: nel CSS a parita' di specificita' vince chi arriva dopo, e queste
 * regole erano scritte per sovrascrivere quelle dei fogli caricati sopra.
 * Spostarle piu' in alto ne farebbe smettere di funzionare una parte, in modo
 * sparso e difficile da collegare alla causa.
