App icon rasterize (SVG → 1024 PNG)

Use when a designer hands off the icon as SVG and you need the PNG that AppIcon.appiconset/Contents.json references.

This is the gap discovered during first-pass icon production on a real project — the SVG → 1024 PNG step was undocumented (only the downstream Pillow Lanczos downscale to the macOS ladder was written up). Each appearance — Light, Dark, Tinted — is a single 1024 universal PNG produced by exactly one rasterize step, documented here. (Tinted is now a standard third appearance alongside Light and Dark; all apps in the reference project ship AppIcon-Tinted.png.)

When to use

• Designer subagent (or human designer) produced a clean light.svg + dark.svg + tinted.svg matching the icon spec
• You need the matching AppIcon-Light.png + AppIcon-Dark.png in <app>/Assets.xcassets/AppIcon.appiconset/
• No rsvg-convert / inkscape / imagemagick and no Homebrew — qlmanage (QuickLook) ships with macOS and is the rasteriser of record here (this skill exists precisely for the no-Homebrew case)

When NOT to use

• The SVG uses <filter> blurs, <text>, embedded fonts, or other features QuickLook's SVG generator may render unreliably. Re-author the SVG with flat shapes first.
• The SVG already ships as PNG from the designer (e.g. Affinity / Figma export). Just commit the PNG.
