Screen readers got no signal that a dialog opened — not one modal carried
role="dialog" — and several close buttons had no accessible name.
- The 6 static tool windows (Brain, Theme, Prompt, Rename session, Cookbook,
Settings) now carry role="dialog" + an accessible name. They are dockable,
tiling windows, so they are non-modal dialogs (intentionally no aria-modal).
- The four unlabelled close buttons (theme, prompt, cookbook, settings) get an
aria-label so they no longer read as just "heavy multiplication x".
- styledConfirm / styledPrompt ARE blocking modals: they get role="dialog" +
aria-modal="true" + aria-labelledby/aria-describedby, and now manage focus —
restore focus to the triggering element on close and trap Tab within the
dialog (they already moved focus in on open).
tests/test_dialog_aria.py pins the roles, labels, and focus management.
