Weekdays that fit the weather columns, the top bar's own abbreviation, tile texts that fit, and a check that measures them

- The CYD's weather columns hold two letters beside the icon: every language has its own two-letter days (the CLDR's
  short width, Polish nd pn wt); French mar became nar there. check fails on a longer one.
- The top bar takes the language's abbreviation (sam. 19 sept., Sa., 19. Sept.), English keeps Sa 19 Sep.
- The editor's clock and date follow the screens: 7:05 PM in the top bar, 7:05 on the clock card.
- A long weather word ends in an ellipsis before the days.
- Tile lines that were cut on a screen are shorter (Zum Öffnen, Ouvrir, Otwórz, Sin imagen, ...); check measures
  them with the screens' font against the tile width of both boards.
