Start by reproducing quarto install tool tinytex on Windows 10 with an interrupted connection, using the reported Quarto CLI version 0.9.596 as a reference. Trace the CLI's TinyTeX download path and determine how interrupted downloads are handled. Done means a temporary connection interruption does not require the approximately 200 MB download to restart from the beginning.
