FUNDISHA.SITE v33 — SonicPesa Access Key + Secret Key

This version keeps the existing FUNDISHA.SITE design and account/payment flow,
and replaces the payment authentication with the Access Key + Secret Key
system from the supplied nw_v25 payment package.

1. Upload/extract the contents into your existing website folder:
   public_html/zungu/a/

2. In config.php, fill ONLY these two credentials:
   const SONICPESA_ACCESS_KEY = 'YOUR ACCESS KEY';
   const SONICPESA_SECRET_KEY = 'YOUR SECRET KEY';

3. You can change the payment amount here:
   const SONICPESA_PAYMENT_AMOUNT = 200;
   Example: 300, 400, 500.

4. Do NOT put the keys in script.js, index.php, or HTML.

5. The server sends:
   X-API-KEY: Access Key
   X-API-PASSWORD: Secret Key

6. PHP + cURL are required.

7. Payment amount is controlled by the server. The browser cannot choose the
   final amount.

8. Countdown/access is only produced after the server confirms SUCCESS.

9. The API files are:
   api/payment_create.php
   api/payment_status.php

Important: never share your Access Key or Secret Key in chat/screenshots.
