Browser-based viewer for DocLang markup and archives: a reading view, formatted markup, and—when opening an archive with page images—original pages with linked selection and bounding-box overlays.
Standalone .dclg or .xml files show markup and the reading view only. .dclx archives may also include page images and assets; layout and page-alignment rules are in the DocLang specification (archive format section).
Serve this directory over HTTP so the demo can fetch example files:
python3 -m http.server 8080Open http://localhost:8080/ and click Load demo.
