App Icon

Generate a store-quality launcher icon (iOS App Store icon + Android adaptive icon + web favicon) for an Expo / React Native app, then post-process it to meet store requirements.

<aesthetic_target> The target is a premium, vibrant, dimensional icon like top App Store featured apps — NOT a flat pictogram. See references/ for the north star:

• references/example-character-mascot.webp — what this recipe produces for a character app (glossy 3D mascot + heart, full-bleed warm gradient).
• references/example-symbol-object.webp — what it produces for a symbol / monochrome brand (glossy 3D spark on a deep ink background — proof a one-color brand still gets a dimensional icon, not a flat glyph).
• references/inspiration-premium-icons.webp — external inspiration (soft glossy blob mascot on a vivid gradient tile).

The look every time: one dimensional hero (a soft glossy 3D character/mascot, or a bold symbolic object/abstract form) with smooth gradients, soft studio lighting, gentle rim light and a subtle glow, centered on a full-bleed vivid branded background that reaches all four edges. Saturated, high-contrast, polished, delightful.

The #1 failure to avoid: a flat monochrome pictogram / black-on-white glyph / line icon on a plain white background. If the output looks like an SVG symbol, it is wrong — regenerate. </aesthetic_target>

<capability_gate> Use ANY image-generation tool you have. Generate the icon yourself; do not just hand the prompt back if you can run a tool.
