/* Layout: a dark trading app. A sign-in screen first; then one column, phone first, with four views (five for the owner) behind a glass tab bar (bottom on phones, a pill row under the header on wider screens). Cards float on a deep navy ground with a soft blue glow at the top. This design commits to a single dark look. */
