Extract the libheif snapshot into the libheif directory of the Emscripten
build snapshot. Follow its pinned CI workflow and dist-prep.sh to rebuild
the decoder with Emscripten, then use the libheif-js scripts/install.js and
bundling settings to regenerate the browser module. Consult those source
files for third-party codec source/dependency versions and build options.
No decoder changes have been made. You may replace the separately served
/vendor/libheif/libheif-bundle.mjs with a compatible rebuilt module.

The application does not restrict modification/replacement of these LGPL
components or reverse engineering required to debug such modifications.
Other application materials remain under their own terms.
