// "Use Txts" is locked on for now: the current D2RLoader.exe
// requires it. Toggle this flag back to false once the loader
// supports running without -txt.
//
// Order matters: this controls BOTH the visual layout of the 2x3
// grid AND the order in which flags appear in the launch-args
// string. The grid fills left-to-right, top-to-bottom
// (col = i%2, row = i/2):
//
//   [0: Use Txts  ] [1: Respec     ]   <- top row
//   [2: Window    ] [3: Reset Maps ]   <- middle row
//   [4: No Sound  ] [5: Skip Intro ]   <- bottom row
//
// BuildLaunchArgs walks this array in order, so the cmd preview reads:
//   -mod MODNAME -txt -enablerespec -w -resetofflinemaps -ns -skiplogovideo -seed VALUE
// (-seed is appended last by BuildLaunchArgs from g_modSettings.seedArg
//  when non-empty; the seed UI lives in its own row below the flag
//  grid.)
