- Backup ZIP (download and automatic per-user server backups) carries the
files of the user's own notes as media/<id><ext>; restoring creates
them with new IDs and rewrites the blocks.
- Markdown archive puts them under attachments/ and embeds them relative
to each note (); re-importing turns them
back into image/audio blocks.
- Obsidian import takes images and audio a note embeds on its own
(![[file.png]], ); unused or invalid files appear as
skipped in the preview instead of vanishing.
- Format detection and file paths moved into storage for this.
