## WEGWERF-Renderprobe (Karte t_1cdc1a72, Lauf-Modus im Map Builder selbst) —
##   (a) Spieleraugen-Startansicht am Team-0-Spawnpunkt (Kisten voraus, HUD an)
##   (b) Nach 8 m Gehen (60 × step 1/30 s) — Spieler bewegt, bleibt auf Terrain
##   (c) Nach ESC: Editor-Panels wieder da, Spiel-Kamera weg, Status meldet
## Ausführen:
##   xvfb-run -a godot4 --path . --rendering-driver opengl3 -s res://tests/probe_playtest_render.gd
## Wegwerf-Probe (nicht im Repo-Commit — Datei-Grenzen der Karte), Beweise nach
