# Dry-run plan: describe what a generation run WOULD produce (directories, page
# and redirect counts, the planned tarball name) without writing anything. Moved
# out of album-metadata.source.sh (task 6r0): previewing a run is its own concern,
# distinct from the EXIF presentation that stays in the album module. The plan
# depends on count_incoming_images (image.source.sh) for the image tally and
# tarball_name_plan (archive.source.sh) for the planned archive name; both are
# sourced before this module and called at runtime, so source order documents the
# dependency without affecting availability. dry_run is the CLI entry point wired
# up from action.source.sh. Behaviour and signatures are unchanged by the move.
