images-inline — stable

The convention this extension declares: images are not a separate field — a message whose content is a data URI (data:image/...;base64,...) or raw base64 carries an image inline. Declaring it tells other readers what to expect; it adds no fields and changes no behavior.

• Fields: none beyond core — content carries the payload; kind: "image" is a common optional marker.
• Readers never decode or transform content, and files never carry a byte-order mark (see SPEC, "File shape").
• Status: stable. Emitted by the curtis plugin, porter, curtis-web, curtis-cloud, and curtis-ai-tech.

A practical consequence, stated in the spec's implementation notes: a small conversation with images may legitimately be a large file. Treat .curt files as untrusted input and bound parsing by size before validation.
