   SHUFFLE DAW — la machine dépliée en plein écran (ui/daw.js, ADR-58)
   html.sd-daw : la .machine devient une fenêtre fixe plein écran ; son
   en-tête (LCD, roue, knobs, boutons, mixer) reste tel quel ; le
   compartiment des onglets laisse la place à l'ARRANGEMENT (#daw-root) ;
   les onglets s'ouvrent en FENÊTRES FLOTTANTES (.daw-float).
