$ ./pandoc -f native -t typst
[ Para
    [ Cite
        [ Citation
            { citationId = "a-ref"
            , citationPrefix = []
            , citationSuffix = []
            , citationMode = NormalCitation
            , citationNoteNum = 1
            , citationHash = 0
            }
        ]
        [ Str "[@a-ref]" ]
    , Str "b"
    ]
]
^D
@a-refb
$ ./pandoc -f markdown -t native
[@a-ref]b
^D
[ Para
    [ Cite
        [ Citation
            { citationId = "a-ref"
            , citationPrefix = []
            , citationSuffix = []
            , citationMode = NormalCitation
            , citationNoteNum = 1
            , citationHash = 0
            }
        ]
        [ Str "[@a-ref]" ]
    , Str "b"
    ]
]

Shouldn't there be a separator there? Something like @a-ref#(/* nothing */)b.
