- `encrypted`: `true`
- `app`: `SkyeDocxMax`

## HTML ZIP Archive

SkyeDocxMax also exports a self-contained HTML ZIP archive for local review and re-import.

Archive files:

- `manifest.json`
- `document.html`
- `document.txt`
- `<title>.html`
- `assets/*` for embedded binary assets

Manifest fields:

- `format`: `skyedocxmax-html-archive`
- `version`: `1.0.0`
- `app_id`: `SkyeDocxMax`
- `title`
- `document_id`
- `exported_at`
- `html_entry`
- `plain_text_entry`
- `asset_directory`

Honest boundary:

- This archive is for local HTML/TXT portability and SkyeDocxMax re-import.
- Same-folder browser runtime proof comes from File System Access handle/open/save evidence, not from pretending this ZIP is a `.docx` container.
- It is not a Microsoft Word/OpenXML `.docx` package.
