The `/errors` window wears the ClassTrainer panel art, but its Clear and Close buttons sat at y −455, below the art, and its detail pane ran to −442, into the button sockets.
On that art the class trainer lays out (`Blizzard_TrainerUI.xml`, `ClassTrainer_SetToClassTrainer`):
- a 296×184 list at (−67, −96) from the top right, with 11 rows;
- a 119-tall detail pane 8 below the list, ending at −407;
- Train and Exit, 80×22, centred at (224, −420) and (305, −420).
The log now uses those frames: Clear and Close sit in the sockets, the detail ends above them, and the list shows 11 rows, not 13.
The new test lays out the stock trainer and the log in one UI and checks that each log frame equals the trainer's, with the buttons inside the window. It fails on the old layout.
