Pandoc reads markdown, so every Word export had to flatten the resource to
markdown first — and a deck flattened to markdown stops being one. A comparison
became two headings and two lists, a callout became bold text, and a figure
became nothing at all, because markdown has nowhere to put it.
src/utils/docSpec.js reduces either source to the same blocks: a stored deck
where there is one, the markdown where there is not. scripts/render_docx.py
draws them. A comparison comes out as a labelled two-column table, a callout as
a shaded box, a table as a real table, a figure embedded at its own aspect ratio
with its caption, and speaker notes as muted indented text.
The deck wins over the markdown beside it, because that markdown is a
serialisation of the deck and reading it instead would be reading a lossy copy of
what is right there.
Word now carries the figures too. The export route skipped fetching them for
docx, which was correct when pandoc could not place them and wrong the moment
this could.
Pandoc stays installed and stays the fallback: a plainer document beats a failed
download. Both renderers now share one spawn helper.
Verified end to end: a deck with two figures exported as a six-page Word document
with both images embedded (537KB, two files in word/media), rendered to PDF and
looked at — the comparison is a labelled table, the figure sits at its true
aspect ratio, and the notes read as notes.
