To save on page size, pre-render LaTeX.
Today the whold library (~1mb) is served on every page...

I tried and failed on the old repo. Retry !

Previous notes :

MathJax js LaTeX library is 1mb. that's too much (goal : 1mb max on every page)
KaTex js LaTeX library is only 0.26 mb, but that is still uncessary. Also it has trouble rendering inline LaTeX like a + b = c when there also is $ in the text.

It is possible to use render hooks to render latex server side, thus ligntening download size
