Motion edit prompt

Keep the document outline and folded corner stationary. Animate the three horizontal writing lines by revealing each stroke from left to right, not by moving them as solid bars. Begin the loop with the lines hidden and the pen resting at the lower-right of the page in its existing diagonal tilt, tip aimed down-left. The pen first travels smoothly up-left to the left start of the top line, then glides right along that line while the stroke is revealed left-to-right just behind the pen tip. The pen then dips down-left to the left start of the middle line and repeats the same rightward writing motion once, revealing the middle stroke left-to-right. Next it dips down-left to the left start of the shorter bottom line and writes that stroke left-to-right. After the bottom line is complete, the pen moves back down-right to where it sits in the provided SVG near the page edge; at the loop reset, gradually shrink all three written lines back to their left ends over a brief beat so the page becomes blank again before the next writing pass begins.
