dwindown c1f09041ef docs: Shipping field hooks + Tax selling locations strategy
##  Issue #1: Shipping Fields - Addon Responsibility

Created SHIPPING_FIELD_HOOKS.md documenting:

**The Right Approach:**
-  NO hardcoding (if country === ID → show subdistrict)
-  YES listen to WooCommerce hooks
-  Addons declare their own field requirements

**How It Works:**
1. Addon adds field via `woocommerce_checkout_fields` filter
2. WooNooW fetches fields via API: `GET /checkout/fields`
3. Frontend renders fields dynamically
4. Validation based on `required` flag

**Benefits:**
- Addon responsibility (not WooNooW)
- No hardcoding assumptions
- Works with ANY addon (Indonesian, UPS, custom)
- Future-proof and extensible

**Example:**
```php
// Indonesian Shipping Addon
add_filter('woocommerce_checkout_fields', function($fields) {
    $fields['shipping']['shipping_subdistrict'] = [
        'required' => true,
        // ...
    ];
    return $fields;
});
```

WooNooW automatically renders it!

##  Issue #2: Tax - Grab Selling Locations

Updated TAX_SETTINGS_DESIGN.md:

**Your Brilliant Idea:**
- Read WooCommerce "Selling location(s)" setting
- Show predefined tax rates for those countries
- No re-selecting!

**Scenarios:**
1. **Specific countries** (ID, MY) → Show both rates
2. **All countries** → Show store country + add button
3. **Continent** (Asia) → Suggest all Asian country rates

**Smart Detection:**
```php
$selling_locations = get_option('woocommerce_allowed_countries');
if ($selling_locations === 'specific') {
    $countries = get_option('woocommerce_specific_allowed_countries');
    // Show predefined rates for these countries
}
```

**Benefits:**
- Zero re-selection (data already in WooCommerce)
- Smart suggestions based on user's actual selling regions
- Scales for single/multi-country/continent
- Combines your idea + my proposal perfectly!

WooNooW

WooNooW is a modern experience layer for WooCommerce — enhancing UX, speed, and reliability without data migration.
It keeps WooCommerce as the core engine while providing a modern React-powered interface for both the storefront (cart, checkout, myaccount) and the admin (orders, dashboard).

Three Admin Modes:

  • Normal Mode: Traditional wp-admin integration (/wp-admin/admin.php?page=woonoow)
  • Fullscreen Mode: Distraction-free interface (toggle in header)
  • Standalone Mode: Complete standalone app at yoursite.com/admin with custom login

🔍 Background

WooCommerce is the most used ecommerce engine in the world, but its architecture has become heavy and fragmented.
With Reactbased blocks (Checkout, Cart, Product Edit) and HPOS now rolling out, many existing addons are becoming obsolete or unstable.
WooNooW bridges the gap between Woos legacy PHP system and the new modern stack — so users get performance and simplicity without losing compatibility.


🚀 Key Principles

  • No Migration Needed Woo data stays intact.
  • Safe Activate/Deactivate revert to native Woo anytime, no data loss.
  • Hybrid by Default SSR + React islands for Cart/Checkout/MyAccount.
  • Full SPA Toggle optional Reactonly mode for max performance.
  • HPOS Mandatory optimized datastore and async operations.
  • Compat Layer hook mirror + slot rendering for legacy addons.
  • Async Mail & Tasks powered by Action Scheduler.

🧱 Tech Stack

Layer Technology
Backend PHP 8.2+, WordPress, WooCommerce (HPOS), Action Scheduler
Frontend React 18 + TypeScript, Vite, React Query, Tailwind (optional)
Build & Package Composer, NPM, ESM scripts, Zip automation
Architecture Modular PSR4 classes, RESTdriven SPA islands
