                            WHAT YOU NEED TO DO
================================================================================

STEP 1: Install QR Code Package
  $ composer require simplesoftwareio/simple-qr-code

STEP 2: Run Migrations
  $ php artisan migrate

STEP 3: Update routes/web.php
  Add this line after other route includes:
  include __DIR__ . '/qr-and-storage.php';

STEP 4: Integrate in WillTemplateController
  - Use QrCodeService to generate QR codes
  - Use EstateAndStorageService to store documents
  - Use FuneralInstructionsService in PDF generation

STEP 5: Create Views
  - Funeral instructions form
  - QR verification page
  - Document storage dashboard

STEP 6: Test
  $ php artisan tinker
  > \App\Services\QrCodeService::generateVerificationToken('will', 1)

                         FEATURE 1: QR CODE SYSTEM
================================================================================

WHAT IT IS:
  QR codes embedded in PDF documents for verification

HOW IT WORKS:
  1. Generate unique token: SHA256(type + id + timestamp + secret)
  2. Create QR code image containing verification URL
  3. Embed QR in PDF header/footer
  4. Client scans with phone → Opens verification page
  5. Shows document info + scan history

  Controller:  app/Http/Controllers/QrCodeController.php
  Route:       POST /qr-codes/will/{will}/generate
  Public URL:  GET /verify/qr/{token}

USAGE:
  $token = QrCodeService::generateVerificationToken('will', $will->id);
  $qrCode = QrCodeService::generateQrCode($token, 300);
  // $qrCode is base64 encoded PNG image

BENEFITS:
