ECO-CODES v0.2.0
By Swift4Data — Mobile barcode + OCR scanner

FIRST RUN
---------
  Double-click ECO-CODES.exe. Your browser opens to the History page.
  A QR code on that page lets you open the mobile scanner on your phone
  (your phone must be on the same Wi-Fi as this computer).

WORKFLOW
--------
  1. Scan the QR with your phone camera → opens the mobile capture page.
  2. Take a photo of a barcoded label → queues as PENDING.
  3. On the desktop History page, click 'Process pending' to OCR them.
  4. Click any OCR cell to correct the value; use the scissors icon
     to crop and re-OCR a region. Export results to CSV when done.

DATA LOCATION
-------------
  All data lives in %APPDATA%\ECO-CODES\:
    scans.db             SQLite database with all scan rows
    uploads\             raw photos waiting to be processed
    uploads\processed\   photos after OCR
    exports\             CSV exports
    .secret              session key (auto-generated, keep private)

DEBUG MODE
----------
  Run ECO-CODES-debug.exe instead of ECO-CODES.exe to see a console
  with logs — useful for port collisions, OCR failures, etc.

UNINSTALL
---------
  Delete this folder. To also wipe scans, delete %APPDATA%\ECO-CODES\.
