Create a 30-SECond full-code-driven animation using SVG vector graphics and synthesized original soundtrack.

Visual Style: Abandon line boiling; use hand-written vector gradients, soft shadows, and night sky glows.

Scene Sequence:
1. A small charACTer steps on the ground, charges up, runs into the sunset, and hits a star which explodes.
2. Sync every action (stepping, charging, running, exploding) precisely to piano and harp notes frame-by-frame.
3. Ending: CuRSIve text "Claude Opus 5.5" does a flip and lands as a decimal point, followed by confetti falling from a blink.

Technical Requirement: Every frame and note must be written by code.
