Hi @tarleb, the root cause of the Typst callout failures is that both with jog and without, the following

quarto-cli/src/resources/filters/customnodes/callout.lua

Lines 46 to 51 in bf93178

	parse = function(div)
	quarto_global_state.hasCallouts = true
	local title = string_to_quarto_ast_inlines(div.attr.attributes["title"] or "")
	if not title or #title == 0 then
	title = resolveHeadingCaption(div)
	end

will initialize callout.title to Inlines({})

However, when the custom node is read later on to generate Typst, content.title is nil on main, but

Plain {
  clone: function: 0x600002f273c0
  content: Inlines {}
  show: function: 0x600002f27450
  walk: function: 0x600002f27420
}

on jog.

quarto-cli/src/resources/filters/customnodes/callout.lua

Lines 264 to 272 in bf93178

	return _quarto.format.typst.function_call("callout", {
	{ "body", _quarto.format.typst.as_typst_content(callout.content) },
	{ "title", _quarto.format.typst.as_typst_content(
	callout.title or pandoc.Plain(_quarto.modules.callouts.displayName(callout.type))
	)},
	{ "background_color", pandoc.RawInline("typst", background_color) },
	{ "icon_color", pandoc.RawInline("typst", icon_color) },
	{ "icon", pandoc.RawInline("typst", "" .. icon .. "()")}
	})

It's not the right solution, because we'd like to understand why it is converting (?) the title differently, but the following diff gets these tests passing:
