"""

P44 OCR Viewer launcher.
|
|
Starts a local HTTP server at port 5044 and opens the viewer in the default browser.
|
|
Run from any directory; the server root is always the project folder (this file's location).
|
|
If port 5044 is already in use (server already running), just opens the browser tab.
