-- `exportSelected(groupIds)` replaces the old `exportAll()` — accepts an array of group IDs to export. Pass `null` or `[]` for a full export. Vault meta (salt, test payload) is always included for import decryption.
-- `ImportExport.svelte` fetches groups/entries on modal open and shows a checkbox list for group selection with live entry count.
+- `exportSelected(groupIds, vaultKey, exportPassword)` — group IDs to export; `null`/`[]` = full export (include `''` for ungrouped). Vault meta (salt, test payload) is always included for plain import decryption.
+  - **Plain export** (no export password): unchanged — entries keep their source-vault-encrypted passwords; import needs the source vault's master password.
+  - **Password-protected export**: pass a `vaultKey` (in-memory) plus an independent `exportPassword`. Re-keys every exported entry's password to the export-derived key and AES-256-GCM-seals the entire payload (titles/usernames/notes included). Returns `{ format: 'encrypted-export', salt, data }`.
+- `importAll(data, mode, sourcePassword, targetKey)` detects a sealed export (`data.format === 'encrypted-export'`): `sourcePassword` is then the EXPORT password and may differ from any vault's master password. A wrong export password rejects the import (it never silently skips entries). The entry loop decrypts with the source key and re-encrypts under `targetKey`.
+- `ImportExport.svelte` fetches groups/entries on modal open and shows a checkbox list for group selection with live entry count. The export dialog has an optional "separate password" field; the import dialog's field is a generic file password (export password for sealed files, source vault master for plain files).
