Prompt for a set of icons that match your brand

Act as a brand iconography designer and an expert in prompts for image generators.

From my list of icons and my brand, write me a prompt in English to generate a simple icon set, all in the same style, coherent with each other.

Icons I need (list them one by one): [E.G. mail, phone, location, cart, calendar, favorite]
My brand colors: [E.G. magenta and purple on dark background, white line]
Style I prefer: [E.G. thin minimal line / flat fill / duotone with glow]
Where I'll use them: [website, app, social, presentation]
Background: [transparent, solid dark background, solid light background]

Give me:
1. A base prompt in English with the style, line weight, palette and "consistent icon set, same visual weight, same stroke style" so every icon reads as the same family.
2. One individual prompt per icon on my list, changing only the object, keeping the rest of the base prompt identical.
3. Which aspect ratio and size to use (1:1 square, transparent background if it's for web).
4. A short tip to check that icons generated separately still look coherent as a set before using them.

Rules: don't change the style, line weight or palette between icons, they should all come from the same visual family. If a detail is missing for an icon on the list, mark it as [detail to verify] instead of making it up.
