# A bounded dialog card drawn in the game's own style: a dark chamfered
# body with a glowing border and bright corner brackets. Chamfered rather
# than square because cut corners read as "console panel" and match the
# hard-edged neon of the buttons and HUD.
#
# Draws itself from its own rect, so it can be sized freely in the scene.
