[NTG-context] Protect the lettrine
I'm using KeenWrite Themes (specifically, Boschet) to typeset a chapter
wherein the first letter is a lettrine. When the first paragraph is too
short, the second paragraph overlaps the lettrine.
% SOT
\setupinitial[n=2]
\setuphead[chapter][
after={\placeinitial},
page=no,
]
\starttext
\chapter{one}
Kermit Ruffins
Meet me at the second line.
\chapter{two}
\input knuth
Meet me at the second line.
\stoptext
% EOT
Produces: https://i.stack.imgur.com/kNDqw.png
How would you instruct ConTeXt to "protect" the lettrine such that
regardless of whether the first paragraph spans multiple lines, a short
first paragraph will still prevent the second paragraph from overlapping
the lettrine?
That is, the setups should work in both cases, without any knowledge about
the first paragraph length being added between \starttext and \stoptext.

Thank you!

But is this true? The following code seems to contradict this:
\def\HOME{myhome}
\writestatus{1}{\meaning\HOME}
\letfrozen\HOME
\writestatus{2}{\meaning\HOME}
\def\HOME{other home}
\writestatus{3}{\meaning\HOME}

Is this mechanism broken? It looks so useful to prevent accidental redefinition!
here i run with
\enabledirectives[overloadmode=error]
(you can do that in cont-sys.mkxl)
\enabledirectives[overloadmode=warning]

Pity. Now I get on loading the tex file:
"csname overload > fatal error, protection level 4, control sequence 'nbsp',
properties 'immutable', file 't-hvdm-text.tex', line 63
while I had hoped that frozen would give me something like:
illegal attempt to redefine \HOME
Byproduct (not unwanted) the above illegal redefinition to be solved :-)
May I ask why obviously the frozen-mechanism seems (yet?) unimplemented?
It's okay and has been around for quite a while now.
\enabledirectives[overloadmode=error]
\starttext
\frozen\def\HOME{}
\def\HOME{!}
