Server notes
Server is 32-bit only (contagionds.exe). Wine requires WINEARCH=win32 + winetricks vcrun2013 vcrun2015 corefonts. appinfo config shows a native Linux binary contagion_dedicated (-secure -steam -game contagion), but the Pterodactyl egg uses Wine to run the Windows version; both approaches coexist.
