* web: the return of pseudolocalization The move to lit-locale lost the ability to automagically pseudolocalize the UI, a useful utility for checking that additions to the UI have been properly cataloged as translation targets. This short script (barely 40 lines) digs deep into the lit-localize toolkit and produces a pretranslated translation bundle in the target format folder. * Linted, prettied, and commented.
