#footnoteRookery’s own #footnote, which shadows Typst’s and scopes a note to the idea it is written in. Import it alongside #idea and write footnotes exactly as before — the single positional argument is the footnote’s body. That import is needed in every file that writes a footnote, since Typst’s imports are per file; an idea body that reaches Typst’s own #footnote instead of rookery’s fails the build, with an error naming the import to add.
#import "@rookery/core:0.1.0": idea, footnote
#idea("etal")[A claim#footnote[The evidence.] worth qualifying.]Inside an idea, the enclosing idea claims the note, numbers it against itself and lists it in its own Footnotes block — on every surface that idea appears on. Outside one, the rule #show: rookery installs falls back to Typst’s own footnote, so a note in ordinary page prose behaves as it always did. See footnotes for what idea-local numbering means for a page carrying several.
