floor_2.ogg note: The nursery/lullaby track is the hardest to find as a pure CC0 loop. Seth_Makes_Sounds/684511 is a gentle, simple game loop that works for a calm nursery atmosphere. If you want a proper lullaby feel, ispeakwaves/384934 (Soft Piano Loop, CC-BY 3.0) is a better fit — just add attribution.

Notes

• All CC0 picks require no attribution, but you may credit anyway.
• Prefer the primary pick; use the alt only if the primary is unavailable or unsuitable on preview.
• Keep music loops between 30–60 s to minimize file size on mobile.
• SFX should be trimmed with a short (~5 ms) fade-out to avoid clicks.
