BT_GLASS is a compile-time #ifdef; getenv("BT_GLASS") appears nowhere in the
tree. The line rode along from the bring-up launcher into the frozen profile
and into the pod-hardware runbook, reading like the switch that turns the
glass path on. It never did anything -- the rig worked because glass is the
DEFAULT profile when nothing is set.
Replaced with BT_PLATFORM=glass (the real spelling, so the cart does not lean
on that default) and noted why NOT BT_PLATFORM=pod: the pod profile selects
the 1995 multi-surface gauge path, which needs the NVIDIA horizontal span no
modern driver has. Behaviourally identical -- both land gBTPlatformGlass=1.
Re-verified on the cart: 9 settings applied, GLASS profile, -fit borderless,
all three surfaces on their intended displays.

The cart's display config was carried by a launcher .bat, so it only came up
right if the game was started one particular way. Move it into the file the
engine already reads before anything touches the environment.
content/environ.ini <- scratchpad/pod/podprofile.ini, merged idempotently
between markers by scratchpad/pod/mergeprofile.ps1
Two gates were missing for that to be enough:
BT_FIT=1 the env spelling of -fit, so the borderless main view does not
depend on one launcher's command line (shortcut, scheduled
task and autostart all have to produce the same rig)
L4PLASMA= NONE / OFF / 0 -> no marquee at all. Leaving it unset does
NOT work: the GLASS profile force-defaults it to SCREEN, which
drops a desktop plasma window on the cab's glass. The boot
banner now reports the live state instead of always claiming
"plasma window".
Also lands the bring-up engine work this depended on: monitor:<name|index>
layout binding (device-bound, not pixel-bound -- desktop rects move when a
display re-enumerates), ",bare" implying frameless, rotation-aware radar
surface sizing, BT_GAUGE_SEC_ROT accepting 0-3 (it silently forced 3 for
anything but 1), 180-degree ExpandPlaneToBGRA, and the BT_POD_CHANMAP /
BT_POD_IDENT / BT_POD_CHANTEST identification gates.
Verified on the cart, build 4.11.813, launcher carrying none of it:
[boot] environ.ini: 9 setting(s) applied
[boot] platform profile: GLASS (PadRIO; plasma off [L4PLASMA])
[cockpit] -fit: borderless 800x600
[glasswin] radar rotation 0 (none)
... all three surfaces on their intended \.\DISPLAYn
No [plasmawin] line in an otherwise-logging run = the ctor never ran.
KB: pod-hardware.md gains the ALPHA-MR section (mapping, the two wiring
deviations, the frozen profile, the session-0 remote-work traps) and its RGB
SPLIT "OPEN: which way is the cart wired" is now SETTLED -- it is splitter
wired, the composite is what lit it. glass-cockpit.md documents monitor:
binding, BT_FIT and L4PLASMA=NONE.
