Detailed Description

Sandboxed file storage for plugins on the plugins FAT partition.

Each plugin gets a private directory <plugins>/data/<id>/ derived from the active plugin's id. The plugin only ever passes a bare filename; the host builds the full path and rejects anything that could escape the folder, so cross-plugin and out-of-sandbox access is physically impossible. Gated on the vFAT file storage (plugin-sandboxed) capability.
