   SPECTRUMWATCH — spectrumwatch.pl
   Kierunek: infrastructure / observability / control room.

   MOTYW PRZEWODNI: "ślad widma" — rząd cienkich pionowych kresek
   o nierównej wysokości. Wzięty z NAZWY produktu, nie z branży, więc jest
   abstrakcyjny i nie da się go pomylić z ikoną firmy alarmowej. Występuje
   w czterech skalach i NIESIE ZNACZENIE: brakująca kreska to wykryta
   anomalia. Ozdoba i komunikat to jedno.

   JĘZYK: polski tam, gdzie czytelnik czyta zdania. Angielski tam, gdzie
   patrzy na odczyt maszyny (telemetria, statusy, log). To nie jest
   niedokończone tłumaczenie, tylko podział na język i przyrząd.

   ZIELEŃ JEST OSZCZĘDNA. Oznacza wyłącznie: aktywność, zdrowie systemu,
   potwierdzenie, element interaktywny o najwyższym priorytecie. Kolory
   statusów (warning/critical/info) są od niej NIEZALEŻNE i nie są
   dekoracją.
