It enables range-based operations in native controls while restricting standard Range mutations to preserve encapsulation. It integrates cleanly with existing selection/editing behavior and closes a long-standing gap.

The proposal has evolved from FormControlRange into OpaqueRange. OpaqueRange is a specialized, live AbstractRange subtype whose boundary points reference internal nodes within host-defined elements (for example, <input>/<textarea> today, with a path to custom elements in the future). It enables range-based operations over encapsulated content while avoiding exposure of internal DOM nodes. The proposal also updates AbstractRange so startContainer/endContainer can be null, allowing OpaqueRange to return null for those getters while Range and StaticRange continue to return nodes.
