lavrentiy/meridian ? reverse-engineered prompt

Build me a local first DICOM study viewer that runs entirely in the browser with no server and no upload.

I want to open a single HTML page, drop in a study folder or select DICOM files, and review the images in a clean workstation style interface. It should have linked axial, coronal, and sagittal MPR views, a 3D volume view, and a series browser so I can switch between studies and series easily. Make the crosshair and slice position stay linked across views, with proper localizer lines and windowing controls, plus tools like measure, probe, invert, colormaps, cine playback, and PNG snapshot.

Please keep it fully offline and portable, so it works from a local folder. If the browser needs a local web server for file picking, that’s fine, but there should still be no backend. It would be great if the app remembers measurements and annotations per study in the browser. Look up current browser and DICOM handling docs online if you need to.
