Live preview (--watch)

texmark sources/main.md --pdf --watch

Rebuilds whenever the input markdown, bibliography, or template changes. Combine with an auto-reloading PDF viewer (zathura, evince, okular) for a live-preview workflow — the output PDF is rewritten in place so viewers that follow inode changes keep your scroll position.

In multi-file projects --watch also tracks every embedded chapter and every companion document (plus each companion's bibliography and template). See Multi-file projects for the details.
