# Reference: Agrippina Vaganova, "Basic Principles of Classical Ballet" (Chassé à la seconde)
# Reference: Royal Academy of Dance (RAD) Classical Ballet Syllabus
# Review status: Experimental (ballet UAT; pending peer review with dance-domain educator)
# Biomechanical note: Chassé (from French chasser, "to chase") is a traveling step-together-step
# movement where one foot glides along the floor into demi-plié and the other foot chases and closes
# into first position. First-position turnout is sustained throughout. Floor foot-pins act as stance-foot
# anchors during gait travel while the opposite leg reaches into the step.
