+// Logseq Import Plugin — backend route handler.
+//
+// Registers POST /api/import-logseq which accepts a Logseq vault ZIP upload and:
+//   1. Copies vault assets into public/uploads/ with randomized filenames
+//   2. Rewrites markdown image references to point at the new upload paths
+//   3. Strips Logseq-specific bullet outline prefixes and property blocks
+//   4. Creates a card per journal entry (date-titled) and per page
+//   5. Places everything in an "import" bucket (created if missing)
