Build me a heartfelt interactive apology website called “I Made This For You” that feels warm, emotional, and a little playful. It should walk the person through 11 short sections, starting with a gentle intro, then honest reflection, a real apology, what I should have done instead, no excuses, things I appreciate about them, a tiny choice based mini game, a music section, one last message, and a calm final screen.

Make it feel special with an animated starry background, floating hearts, a soft cursor glow, and a few subtle interactive moments like flip cards and before and after cards. Add a simple music player for a background song with play, pause, volume, and progress controls. Include a hidden easter egg somewhere near the end.

Keep it as a static site that opens directly in the browser with HTML, CSS, and vanilla JavaScript. Make it responsive and beautiful on both desktop and mobile, and if you need to check anything, look up current docs online.
