-//TODO: list problems as FEN (quickly rendered), by date, with possible filtering per variant(?)
-//click on a problem ==> land on variant page with mode==friend, FEN prefilled... ok
-
-// get 10 first problems, and buttons next<>previous send date + "before" or "after"
-// need database: sqlite !
-
-// form "new problem" fen(position/turn/flags[guess]), instructions, solution (mandatory)
-// ==> upload on server in sandbox
-//
-// Atomic rules, atomic game, atomic problems(list drawn position
-// + summary(first chars of instructions) + timedate)... one big Vue ? with components
-//
-// click on problem ==> masque problems, affiche game tab, launch new game Friend with
-// FEN + turn + flags + rappel instructions / solution on click sous l'échiquier
