Repeating row pattern with an icon (or thumbnail image) on the leading side, a heading, and a body paragraph. Use for "what we do", "key features", "what's included", or "how it works" sections — anywhere the same visual pattern repeats 3–6 times for parallel ideas. Distinct from `kv-list` (terms + values) and `objectives-box` (bullets) — feature-row carries enough body text to stand on its own.
