/* Portrait phones — dedicated mobile portrait hero composition.
   The hero photograph is a wide panoramic (1280x590, aspect 2.17). On a
   tall narrow portrait viewport we cannot show the whole image at full
   height AND full width — we have to choose. The chosen approach:

   1. Use the upper portion of the photograph as the visual hero/banner
      (image occupies ~70-75% of the hero vertically).
   2. Push the text content below the image via padding-top so it never
      overlays the important subjects (man face, robot head).
   3. Position the image so both subjects fall in the visible window.

   Two media-feature matches are used for safety across Android browsers
   that may differ on (orientation) support: orientation:portrait AND
   max-aspect-ratio:1/1 (either match means portrait). The cascade puts
   these rules last so they win against the width-only rules above. */
