[Design task] Graphics and cards with participants bios for printing

Your territory, you know best.

Of course the sooner the better, but we all have things to do so whenever you think it’s OK to have it ready @KiraVde.

Made the last changes to the program and added the rooms. Everything in between slots (10:45 - 11:00; 16:15 - 16:30) are coffee breaks, which you can add separately @CamTesta. Again, looking forward to see how it comes out!
