Internal-page hover popups now show the source's monogram alongside
the title / abstract / metadata when one exists. Two-column grid is
gated on .has-monogram so popups for pieces without an authored mark
keep their default single-column body. The serialised SVG comes from
the rendered page's own .frontmatter-mark--monogram figure, excluded
when it is the symmetric-layout placeholder roundel so empty-slot
pieces do not get a fake mark in the preview.
