9.41.3.1 Dimension too large while using pgfplots with gnuplot and tikz decoration

https://tex.stackexchange.com/landing/r/digest?cta=question&id=688969

I use the following code ( with MikTeX latest version and GNUplot 5.4.8 ) to do the parametric plot : 
\documentclass{article} 
\usepackage[dvipsnames, svgnames, table]{xcolor} 
\usepackage{pgfplots} 
\... 
[tikz-pgf] [pgfplots] [gnuplot]

9.41.3.2 Add a latex code before and after every \newtheorem

https://tex.stackexchange.com/landing/r/digest?cta=question&id=688762

I define a few theorems with amsthm's \newtheorem, and I want to prepend and append an hrule for each one of them. Currently I do it with 
\AddToHook{env/a~\200\210env namea~\200\211/before}{hrule code} 
and 
\AddToHook{... 
[amsthm] [hooks]

9.41.3.3 No indent inside tcb theorem

https://tex.stackexchange.com/landing/r/digest?cta=question&id=689258

How would I disable the indents inside my theorem and example boxes which are made by tcbtheorem? Any help would be greatly appreciated.
