Organisation > Devices now sets policy.json `organisation.devices`, each
switch off by default and scoped per domain or group:
- No downloads: attachments and files only preview (reader, conversation
view, Pro tab, list chips, .eml previews, the Files app). Download,
Download all, Open in new tab, Save to Files, drag-out, the browser's
PDF viewer (pdf.js instead) and media download controls go away.
- No export: no .eml export, View source, message drag-out, or folder and
account export; a running export stops and its file is deleted when
the switch turns on. Import stays.
- No printing: no Print buttons in mail, calendar and contacts; Ctrl+P
prints a note; the reader frame prints blank.
- No install prompt: no card, and the browser's own banner is held back.
- Watermark: the user's address and the date over the reader,
previews and every printout (mail, calendar, contacts, plugins).
A message follows its own account's policy; what isn't about one message
follows the strictest signed-in account. Every user path hides its
button, and the anchor and new-tab helpers refuse as a backstop
(lib/download-guard.ts), never the blob readers. The plugin APIs
`ui.downloadFile` and `ui.print` refuse too, and the office editor frame
loses `allow-downloads`.
Two assertions in components/mail/__tests__/blob-routing.test.tsx now
expect `{ kind: 'export' }` as the fifth argument of downloadBlob for an
.eml export: the export says what it is, so the backstop checks "No
export" rather than "No downloads" for it.
