   NOT declaring width/height here, so the img's own HTML width/height
   attributes (or intrinsic size) keep governing its size. Explicitly
   setting width/height: auto was tried and reverted -- for an <img>
   pointing at an SVG with no intrinsic size of its own (like a file-type
   icon), CSS auto sizing ignores the HTML attributes entirely and falls
   back to filling all available width, which stretched a 32x32 icon

   widget's own edges via a negative margin matching its horizontal padding
   (20px, see .widget-area .widget below) -- so the whole row is one
   hoverable/clickable box edge-to-edge, not just the text inside it.

   Some widgets (e.g. a block-editor "Paragraph" block used to hand-type a
   URL) render a link as <p class="wp-block-paragraph"><a>...</a></p>
   instead of <ul><li><a>. :has(> a:only-child) picks out exactly those
