Renders BT's 128x32 plasma display into a desktop window instead of streaming to serial hardware. L4PLASMASCREEN.* copied verbatim from RP412; the L4GREND.cpp selector diff applied (BT's only divergence there is a comment -- no collision). Verified: a 'Plasma Display' window opens and the game ticks normally beside it (L4GAUGE=640x480x16 L4PLASMA=SCREEN). Phase 3b (single-window MFD-split cockpit) is DEFERRED -- blocked on the missing BT cockpit-layout geometry and BT's unfinished upstream MFD dev-composite; the L4VB16 hand-merge is HIGH-risk (BT's dev-gauge docking overlaps RP412's split rewrite). See context/steamification.md and docs/BT412-ROADMAP.md. (Phase 3 of the roadmap) Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
