We wish to support all combinations of the following scenarios:

1. Running notebook installed in SAGE_LOCAL from SPKG
2. Running notebook installed in the system python, or in some venv unrelated to Sage
3. Running notebook on a different host (which has no Sage installation), connecting to the Sage Jupyter kernel (using ssh, or https://pypi.org/project/jupyter-kernel-gateway, or ...)

A. Sage-the-distribution
B. Distribution packaging of Sage (Debian, Conda, ...)
C. Pip-installed sagelib (#30036)

The following data items are relevant:

i. The kernelspec
iii. threejs, jsmol, mathjax data
iiiii. Built Sage documentation

The following installation locations are relevant:

a. data installed with sagelib within the Sage venv, such as src/sage/ext_data
b. data installed within SAGE_LOCAL as part of Sage-the-distribution
c. data installed as "resources" associated with the kernelspec, on the host where notebook runs (see jupyter kernelspec list)
d. data installed as Jupyter nbextensions on the host where notebook runs (see jupyter nbextension list)
