Motion edit prompt

Start from the provided SVG pose. Keep the illustration centered with no rotation, translation, fade, or color change. After a brief still hold, animate the main heart body with 5 elastic scale pulses from a scale origin at the visual center of the heart body: in the first pulse it first scales up uniformly from the resting pose, then scales non-uniformly into a wide horizontally stretched and vertically squashed shape, then scales down past rest into a slightly smaller, taller recoil before scaling up again; use the same wide/short overshoot, smaller/taller recoil, and scale-up return for pulses 2 through 5. After the 5th pulse, reduce the scale motion and settle back to its scale in the provided SVG with 1 tiny final wide-and-short scale overshoot and return. Animate the upper vessel cluster with the same squash-and-stretch pulse but slightly delayed behind the main heart body, using a scale origin at its lower attachment point to the heart, so it expands and compresses just after the body while remaining visually attached, then settles back to its size in the provided SVG.
