/* Slavia Training Programme, guest pages (home, register, pass).

   Emerald is the ground, Electric Green is used only for the one next action,
   everything a guest reads sits on a white card. No web font, no framework,
   nothing in the critical path but this file. Phone first: 390px is the
   design width, and the layout widens only where there is room. */
