Metadata blocks were divs styled with display:table. Nested blocks and orphan cells created phantom columns that squeezed the value column to a character or two. Every metadata block is now a real <table>/<tr>/<td>, which mail clients lay out reliably, and the value column always fills the remaining width. The shared shell gets a gradient hero header, timestamp pill, dark frame, and refreshed section, card, and code-block styling.
