/* ============================================================
   Il riquadro della riconnessione, in stile Aurora.

   Nasceva con l'aspetto predefinito di Blazor: scatola bianca squadrata e
   pulsante azzurro. Compare nel momento peggiore — durante una lezione, o
   mentre si registra un video — e un riquadro che sembra di un'altra
   applicazione fa pensare a un guasto piu' grave di quello che e'.

   I colori arrivano dalle variabili di app.css: essendo ereditate lungo il
   DOM valgono anche qui, e il tema scuro viene da se'.
