embed(TEXT) with nothing exported by hand - so a mismatch is a refusal that \
names both digests rather than a shared library that loads and misbehaves. \
Name what you want: 'all' installs both halves, 'runtime' and 'model' one \
each. Run with no component at all and it reports what is installed and \
downloads nothing, which is what stops a 620 MB fetch being a surprise; \
'--status' does the same explicitly. About 620 MB the first time and \
nothing on a later run. '--residency' chooses when the model is in memory: \
'resident' keeps it, which is about 1.9 GB held and 12 to 36 ms a query; \
'on-demand' loads it per call, which holds nothing and costs about 0.8 s a \
query; 'idle' or 'idle:90s' loads it on use and drops it after a quiet \
