Use the visible SVG as the final assembled pose. Begin with the entire gate hidden: scale the bottom platform to nothing around its center footprint, scale the left pillar assembly and right pillar assembly to nothing from their bases, and move the rectangular middle beam and ornate roof assembly straight up until both are fully above the top edge of the view. First, scale the bottom platform up from its center footprint, overshooting slightly larger before settling to its final size. Next, scale the left pillar assembly upward from its base, including its foot and cap, with a small overshoot and settle; then repeat the same growth animation for the right pillar assembly. After both pillars are in place, drop the rectangular middle beam straight down from above until it lands across the pillar tops; ease the landing and briefly compress the whole assembled structure vertically around the bottom edge before rebounding to normal height. Finally, move the entire ornate roof assembly straight down from above into its final position on the beam, keeping all roof details locked together; on impact, squash the full gate vertically again, then rebound cleanly and hold still. Keep all parts opaque and preserve their final layering, with no rotation.
