# Headless checks of the walkable area and the sounds, built natively on Linux (WSL) from the shared loader:

#   walkviz <apk[+vista]> out.png [cell r radius r gap g]   top-down picture (PX=6 for sub-cell edges, PROBE="w x,z;...")
#   walkfeel <apk[+vista]>       simulated stick walking: leaving the area (must be 0), kept distance, judder
#   walkcompat save|check <apk> <file>   a saved area (FWG1 from an older build, or FWG2) against a fresh bake
#   audiotest <file|apk...>      decodes sounds (WAV, MP3, FLAC, Ogg Vorbis / Opus) and homes' ambience
#   walkgaps <apk>               floors left out of the area and what's between them and it
#   listcolliders <apk>          the world's box / sphere / capsule colliders
#   animcheck <apk> <fenv> [sweep s]   a Clay / glTF home's animation from the APK against the baked .fenv (bit for bit)
#   animrender <home> <prefix> <size> <t,t,...>   the home drawn at those animation times (APK against .fenv)
#   wallcheck <home> [drawn]    invisible walls at every angle: no walkable area inside them (exit 2 if there is)
#   bakecmp <home> <home>        both baked as they load, byte for byte (a .fenv's scene re-baked against its APK's bake)
#   fenv-tool report <apk[+vista]|fenv>   the home report (home_report.h), as Frame Studio and Frame Home make it
#   worldrender <apk> <prefix> <size> [seats|spots|cams x,y,z,yaw,pitch ...] [view=N hide=bits world]: the home rendered with the area and
#                                Auto-generate's items. Lavapipe can't run the renderer: build it with the MinGW
