  Madinah Mushaf page — same proportion as the Store app / printed page.

  Page  510.236 × 729.448
  Frame 390.973 × 600.732 at y=64.36  (pages 3–604)
  Opening frame 283.275 × 398.981 at y=165.233 (pages 1–2)

  The page is contained in the viewport (never stretched). Side mint-green
  on a wide window is the app chrome, not extra padding inside the Mushaf.
