• assert returning a str from __rich_console__ iterates character-by-character emitting each char on its own line, while returning a list of str or yielding str emits whole lines
• assert yielding a non-renderable primitive like int or object inside __rich_console__ raises rich.errors.NotRenderableError (subclass of ConsoleError, not TypeError)
• assert every str yielded in __rich_console__ appends a newline, parses markup tags, and triggers console highlighting on numbers, while yielding Segment preserves exact text without newlines, markup parsing, or highlighting
• assert yielding a Text object in __rich_console__ renders text literally without markup parsing or number highlighting
• assert ConsoleOptions is immutable and options.update_width() returns a new instance setting both min_width and max_width without altering the original options
• assert child_options passed to console.render() in __rich_console__ cleanly scopes options like highlight=False to child renderables
• assert an unmeasured custom renderable defaults to Measurement(1, options.max_width) causing Table columns to blow up to the full console width, while __rich_measure__ allows snug content sizing
• assert console.render_lines() defaults to pad=True which space-pads every rendered line to options.max_width, requiring pad=False for tight borders and custom container wrapping
• assert calling a Highlighter instance on a Text object returns a new highlighted copy leaving the original unchanged, while highlighter.highlight() mutates in-place
