Start with a 1024×1024 px PNG with a solid or opaque background — no transparency, since the App Store does not accept transparent icons. Use sRGB color profile for broadest compatibility. Avoid very thin lines (1–2 px at 1024 px scale become invisible at 29 px). The resizer downsamples with Lanczos3 for sharp edges at all sizes.
