/* =============================================================================
   style.css

   the one stylesheet for metrove.app: a light, neutral product page.
   - system font, near-black text on white, light gray bands between sections
   - .phone frames a screenshot or the live board's video as an iphone, its
     island drawn over the top of the picture
   - .feature rows put text beside a phone (.flip puts the phone first) on
     wide screens, stacked on narrow ones
   - .looks lays the five looks side by side (a row to swipe on a phone), with
     a widget in each; .steps are ride, earn and build as cards; .board-film
     and .boards show the model railway; .duo-frame is the unfolded iphone duo
     on its side; .cards are the everyday uses
   - .prose sets the privacy policy and support pages as plain reading

   usage:
    <link rel="stylesheet" href="/style.css">
