/* Layout: one-column phone app on a single flat background. No boxes or outlines: faint horizontal
   lines are the only separators, and the one filled shape on a screen is its main button.
   A question's answers sit right under it with short inset separators; questions are set apart by
   more space and a full-width line, so it stays clear which answers belong to which question. */
