/* Very small screens (smartwatch-sized). Apple Watch's viewport is
   roughly 160-250px wide - well under any real phone - so this only
   ever applies there, never on an actual phone or iPad. The header
   logo, subtitle, and footer note are decorative/non-essential during
   live use, so they're hidden to free up all the room for a big,
   easy-to-hit button. Sizing uses vmin (the SMALLER of width/height)
   specifically so the button is guaranteed to stay a true circle and
   fit on screen, no matter how oddly-shaped the watch's viewport is. */
