I created a book that strangely renders with an entirely blank page. There are tons and tons of macros, in dozens of files defined before the document starts, but the document itself starts quite simply with a title page set inside \startfrontmatter. How can I identify what types of preamble information would be causing an entire blank page to render before the document even begins?

This minimum working example won't show me the error, but it does show I simply have \starttext followed by my title and nothing is between that should be rendering an entire blank page.

My minimum working example is here:

\definemakeup[titlepage][align=middle]

\definealternativestyle[titlestyle][\ss\bfd][]
\definealternativestyle[subtitlestyle][\ss\bfb][]
\definealternativestyle[authorstyle][\ss\tfa][]

\starttext % <-- there is no code between \starttext and \startfrontmatter below.
    \startfrontmatter
        \startmakeup[titlepage]
            \titlestyle{My story}
            \blank[big]
            \subtitlestyle{\date}
            \blank[big]
            \authorstyle{My name}
        \stopmakeup
    \stopfrontmatter

    \input knuth

\stoptext
