## #588: Character archetype select panel — shown after "New Game", before loading main.tscn.
## Two cards (Smuggler / Detective). Keyboard (left/right/enter/esc) and mouse.
## Emits archetype_confirmed(archetype: String) or archetype_cancelled on ESC.
##
## ESC cancels without creating a save directory — new_game() fires AFTER confirmation.
