Ahhh, try this syntax, I think that might be outdated:

^{:nextjournal.clerk/visibility :hide}(slurp "")

seems its specifically the slurp, it works locally when jacked in its only when building for the garden

okay on a bit more investigation, the cause is this.

(slurp "src/bb_inkscape_example.sh")

(clerk/html [:pre (slurp "src/bb_inkscape_example.sh")])

can you file an issue with a repro? Might need to escape the string

we treat a string as markup eg for svg
