> This repository contains the open-source **frontend core engine** of MockAddress, for generating authentic-format test addresses and MAC address data across multiple countries/regions.
> Full production site:

-## Project Overview
-
-MockAddress Core is a **pure frontend, zero backend dependency** test data engine designed for developers and QA engineers, providing:
-
-- **Authentic-format address data** conforming to official postal standards (verifiable on Google Maps / Apple Maps)
-- Optional **identity fields + credit card fields** (for form/payment flow testing only)
-- **MAC address generation + vendor lookup + IPv6 Link-Local derivation** and other network test data
-
-All core logic runs entirely in the browser and can be deployed to any static hosting environment (GitHub Pages, Cloudflare Pages, Vercel, etc.).
-
-> **Note**: This repository only open-sources the **engine and base styles**.
-> Large-scale address datasets and production site page templates remain MockAddress private assets for online services.

-## Key Features
-
-- **Multi-Country/Region Address Generation (Engine Support)**
- - Supports generating address structures conforming to local postal standards for multiple countries/regions
- - Address fields include complete information: street, city, state/province, postal code, country, etc.
- - Can be extended with localized fields based on country (e.g., Japanese address hierarchy, Hong Kong bilingual addresses)
-
-- **Authentic Format & Verifiable**
- - Address data is based on official postal/statistical data + OpenStreetMap and other public data sources, cleaned and organized
- - Generated results are designed to be **verifiable on Google Maps / Apple Maps and other mapping services**
- - Suitable for registration forms, payment pages, tax calculation logic, and other scenarios requiring strict address format validation
-
-- **Optional Identity & Credit Card Fields (Testing Only)**
- - Optionally generate name, gender, date of birth, occupation, localized ID number formats, etc.
- - Optionally generate credit card numbers (Luhn-validated), expiration date, CVC, and other fields
- - All identity/card data is **randomly generated and does not correspond to any real individuals or real cards**
-
-- **Batch Export & Automation-Friendly**
- - Built-in CSV / JSON export capabilities
- - Suitable for automated testing, regression testing, CI/CD pipelines for bulk test data injection
-
-- **MAC Tools**
- - Generate MAC addresses in multiple formats (colon, hyphen, dot, no separator, etc.)
- - Vendor identification based on OUI dataset
- - Support for deriving IPv6 Link-Local addresses from MAC addresses
- - All logic runs locally in the browser, suitable for network testing, device simulation, and script development
-
-- **Pure Frontend, Privacy-First**
- - No backend service dependency, all logic completed in frontend JS
- - Optionally save generated results to browser `localStorage`, servers do not store any generated data

-## Usage
-
-### Quick Start
-
-**Option 1: Direct Use (if your data directory is `data/`)**
-
-```html
-
-```
-
-**Option 2: Custom Data Path (Recommended)**
-
-```html
-
-```
-
-### Configuration Options
-
-- **`dataBasePath`**: Base path for your data files (e.g., `'my-data/'`, `'/static/data/'`)
-- **`autoDetectPaths`**: Whether to enable automatic path detection (default `true`, suitable for mockaddress.com's multi-language structure)
-
-> **Important**: If you don't call `configure()`, the code will use default behavior, **completely unaffected by mockaddress.com's normal operation**.
-
-### Available Functions
-
-- `generateUSAddress(state)` - US addresses
-- `generateHKAddress(region, isEnglish)` - Hong Kong addresses
-- `generateUKAddress(region)` - UK addresses
-- `generateCAAddress(province)` - Canada addresses
-- `generateJPAddress(prefecture)` - Japan addresses
-- `generateINAddress(state)` - India addresses
-- `generateTWAddress(county)` - Taiwan addresses
-- `generateSGAddress(state)` - Singapore addresses
-- `generateDEAddress(state)` - Germany addresses
-- `generateTaxFreeAddress(state)` - US tax-free state addresses
-- `generateIdentityInfo(address)` - Identity information
-- `generateCreditCardInfo()` - Credit card information (testing only)

-## Deployment Examples: Cloudflare & VPS (Static Hosting)
-
-> The following steps are for developers who want to deploy mockaddress-core themselves, describing only the simplest path for README purposes.
-
-### Deploy with Cloudflare Pages (Recommended for Frontend / Zero Ops Cost Scenarios)
-
-1. Create a repository on GitHub (e.g., `mockaddress-core`), push this project's code to it.
-2. Log in to Cloudflare, go to **Pages**, select "Create a project with Git provider", and bind this repository.
-3. Build settings:
- - Framework preset: **None / Static Site**
- - Build command: Leave empty (or `npm run build` if you add a build process later)
- - Output directory: Set to project root (or your build output directory)
-4. After deployment, ensure:
- - All JS/CSS load correctly via `
