1// MathJax config expected by pymdownx.arithmatex (generic mode).
2//
3// CRITICAL: only set window.MathJax if it isn't already defined. Material's
4// instant-nav re-executes <body> scripts on every page swap, which means
5// this file runs again — and unconditionally assigning
6// `window.MathJax = {tex, options}` would overwrite the live library
7// (with its typesetPromise / startup / etc.) with a stub config object,
8// silently breaking every subsequent re-typeset. The math on the first
9// page renders because MathJax completes its initial typeset *before*
10// the post-load instant-nav clobber; click any link and the new page's
11// arithmatex spans stay as raw `\(...\)` text.
12if (!window.MathJax) {
13  window.MathJax = {
14    tex: {

27// Belt-and-suspenders typeset boot. typesetPromise is idempotent over
28// already-rendered output, so calling it twice on the same page is
29// harmless. The DOMContentLoaded path covers direct loads where the
30// MathJax library hasn't quite finished setup by the time document$
31// would normally have emitted; document$.subscribe covers Material's
32// instant-nav swaps where DOMContentLoaded does NOT re-fire.
