## T4 (docs/TUTORIAL_DESIGN.md §5): Old Tam's tips in a normal world. Each
## fits its moment, shows once, waits its turn, stays put while you're dead,
## is remembered across sessions, can be switched off or shown again, and
## never runs in the tutorial world.
## Run: godot --headless --path . --script res://tests/test_hints.gd
