Grid-layout selector listbox has no accessible name

[vvallalta-code]

Summary

The grid-layout selector exposes a listbox without a programmatically determinable name. Screen-reader users hear a generic listbox without knowing that it selects a section or grid layout.

Location

• Package: @paperbits/core
• Component: grid-layout-selector
• Used by Add Section commands from src/section/sectionHandlers.ts and src/content/contentHandlers.ts.

Expected behavior

The selector has a descriptive accessible name, and its role and selection semantics accurately represent the interaction.

Acceptance criteria

• Add a stable accessible name using the selector heading or an explicit label contract.
• Confirm whether listbox/option is the correct semantic pattern for the interaction.
• If listbox semantics are retained, expose selected state and keyboard behavior correctly.
• Verify the name, role, and selected state with a screen reader.
