There are some special forms for certain purpose
@bibtex[...]it accepts a string that is bibtex format@include{path}splices an external file (e.g. a generated HTML via external tool) verbatim into the rendered output;pathresolves relative to_tmp/, and editing it invalidates the card's build cache@tr/depends{path}declares that a card's build cache also depends onpathwithout rendering anything or splicing it in;pathresolves relative to the project root. Use it for a hand-authored asset a card links to via a raw script element instead of splicing inline, see tr/depends: hash-only file dependencies for more information
