From Jonathan Dietz, Jr.:

Almost all new displays employ VESA Coordinated Video Timings using Reduced Blanking Timing Version 2 (CVT-RBv2) which adds a small amount of overhead to the video signal. This overhead includes 80 additional horizontal pixels and enough additional lines to meet the 460 µs minimum vertical blanking interval requirement. You can download an Excel spreadsheet from VESA that will do all the calculations for you, but the math is pretty simple:

460 / ((1000000 / [refresh rate in Hz] - 460) / [vertical resolution])

To get an integer number of lines, you round this result down and add 1. So for Pro Display XDR resolution at 120 Hz that would work out to:

460 / (1000000 / 120 - 460) / 3384) = 197.710 = 198 additional lines

<!-- 
  When an input element gets focused, iOS Safari tries to put it in the center by scrolling (and zooming.)
  Zooming can be easily disabled using a meta tag, but the scrolling hasn't been quite easy.

  The main quirk (I think) is that iOS Safari changes viewport when scrolling; i.e., toolbars shrink.
  Since the viewport _should_ change, it thinks the input _will_ move, so it _should_ scroll, always.
  Even times when it doesn't need to scroll—the input is fixed, all we need is the keyboard—
  the window always scrolls _up and down_ resulting in some janky animation.

  However, iOS Safari doesn't scroll when the input **has opacity of 0 or is completely clipped.**

ℹ️ Enable iCloud end-to-end encryption:

• Nobody knows that, but iCloud actually supports end-to-end encryption (see “Advanced Data Protection for iCloud”) but it's disabled by default. If you care about data privacy, you should turn it on.
  • System settings → Apple ID → iCloud → Set Advanced Data Protection to On.
  • System settings → Apple ID → iCloud → Disable Access iCloud Data on the Web.
• It supports almost all the native Apple apps, with the notable exceptions of iCloud Mail, Contacts, and Calendars. See official data protection matrix for more info.
