Motion edit prompt

For the opening pose, first edit the provided static SVG by scaling both sparkle stars down to 0 about their own centers, scaling the coin face and rear rim/side-stripe groups back to full round width, and moving the rear rim and side stripes from the left side to the right side behind the coin so the orange edge is visible on the right. Animate the coin as layered parts: keep the front face, dotted rim, inner circle, and Bitcoin symbol locked together, centered, and upright while the whole front coin subtly squashes horizontally and then returns to the full round width established in the opening setup. Behind the face, move the rear rim and its horizontal side stripes as one group: it starts visible on the right side, slides left first behind the coin as the front face narrows, briefly holds on the left, then slides back to the right while the coin widens again; use smooth eased motion with no rotation. As the front coin narrows and the rear rim slides left, the upper-right sparkle scales up from a point first, the lower-left sparkle follows slightly later at a smaller size, both hold briefly, then they scale back down to points and disappear, with the upper-right sparkle shrinking away slightly before the lower-left.
