[Test report 04] Demo post for layout stress testing (landscape-image)

[Test report 04] Demo post for layout stress testing (landscape-image). Sample text generated programmatically; not a real news event. It checks line height, wrapping and media ratio of English body copy in the Home feed. On a 390px mobile viewport this paragraph must collapse to three lines with a centered Show more control, expand fully on click and collapse again on Show less. A second paragraph verifies multi-paragraph spacing and balance next to dark media blocks. A third paragraph adds enough length to guarantee the clamp threshold triggers, while portrait images and vertical videos keep their true aspect ratio within the max-height constraint.
