+-- #1441: the Magnet Train ride drew a flat white screen.
+--
+--   POKEPORT_GAME=gold POKEPORT_TOUCH=0 \
+--     POKEPORT_DRIVER=tests/drivers/gold_bug1441_test.lua love .
+--   POKEPORT_SHOT_DIR=/tmp/gold-bug1441   (default)
+--
+-- Nothing here is assertable: the bug IS what the screen shows.  The ride
+-- bakes its background out of data.gen2Field.magnetTrain, TILESET_TRAIN_
+-- STATION's sheet and the TOWN palettes, and every one of those was read
+-- under its Gen 1 key, so all four came back nil and GbcPalette's fallback
+-- filled the panel with DMG_SHADES[1].
+--
+-- The run boots into the Goldenrod station, prints whether the four tables
+-- are actually there, shoots the Saffron-bound ride from JUMPTABLE_INIT
+-- through to the arrival, then plays the Goldenrod-bound one back at 1x with
+-- no screenshots in the way -- a human watching the window sees the whole
+-- animation, which is the only place this bug ever showed.
