Launch the camera, take a photo, draw directly on top of it, and save the final edited image as one file.
The saved image is generated from the same canvas you see in the browser, so it matches your drawn edits.
Start the camera first. After taking a photo, draw on the image and save it.
Notes:
• Camera access requires browser permission.
• On some phones, the saved image downloads to the device's downloads/photos area depending on the browser.
• Everything is contained in this single HTML file. No external libraries are used.
