Copy-ready AI prompt

Starts from the current visual reference and project constraints.

Build a forms component named Phone Input in React/Next.js.
Goal: recreate the same overall UI and behavior as the Phone Input reference from a component gallery.
What it needs to communicate: Country code prefix dropdown with phone number input, supporting 6 country codes with flag emojis..

Project constraints:
- Use Next.js 16.2.6 with the App Router, React 19, TypeScript strict mode, and Tailwind CSS v4.
- Do not create a tailwind.config.js file. Use Tailwind v4 utilities and CSS variables where design tokens are needed.
- If you are implementing this inside the same project, use the Prompt font via next/font/google. If not, use the closest equivalent typeface.
- Return production-ready code with imports, responsive behavior, keyboard accessibility, and polished empty, hover, focus, active, and disabled states where relevant.
- Match the reference closely: color palette, spacing scale, border radius, shadows, icon scale, typography hierarchy, and motion timing.

Component-specific expectations:
- Support label, helper, error, disabled, and validation states.
- Ensure keyboard usability and accessible form semantics.
- Avoid unnecessary dependencies unless the behavior truly requires them.
- No explicit color literals were found in the examples. Match the live reference and the project accent color when appropriate.

Props to support:
- label: string — Label above the input
- value: string — Controlled phone number value
- onChange: (value: string) => void — Called with full number including country code
- placeholder: string — default "812 345 678" — Input placeholder
- className: string — Additional CSS classes

Reference usage patterns:
- No examples were documented. Infer a sensible default presentation and one richer usage example.

Feature expectations:
- Country code prefix select with flags
- 6 preset country codes
- Full number value callback
- Controlled input

Output requirements:
- Return complete code, not pseudocode.
- Include all necessary imports and helper types.
- Keep the implementation accessible, responsive, and visually finished.
- Match the reference for color, size, shape, typography, spacing, and interaction states as closely as possible.
- If multiple files are needed, organize them cleanly and explain the file structure briefly.

Tweak only product-specific copy or data after the first generation pass.
