Biological diagram infographic titled "Piano Action Anatomy" centered on a clean labeled cross-section of an upright piano action mechanism, editorial-grade technical cutaway with biologically accurate-style component labeling adapted for mechanical anatomy, sketchnote visual style, high-contrast modern palette with charcoal black lines, electric blue, vivid orange, lime accents, warm white background, precise engineering mood, medical-textbook clarity, editorial scientific illustration, vector-clean lines, no photographic textures. Show 8 labeled components with thin leader lines, short labels in English, and one-line function descriptions in English: "Key" — "Transfers finger force into the action."; "Capstan" — "Pushes the wippen upward during key motion."; "Wippen" — "Main lever that coordinates jack and hammer movement."; "Jack" — "Escapes from the hammer butt to release the strike."; "Repetition Spring" — "Helps reset the action for rapid replay."; "Hammer Butt" — "Receives force and pivots the hammer assembly."; "Hammer Shank" — "Carries the hammer head toward the string."; "Hammer Felt" — "Strikes the string to produce tone."
