The same page on every screen

The text is laid out on a page of one fixed size and the sheet scaled to
the screen, so a phone breaks it exactly where a desktop does — twenty-one
lines to the page on both. The type size is computed from the page and the
line count rather than chosen.

A PDF's full screen is the browser window, not the screen, and its button
sits beside the zoom. "Recent Notes" is stamped by every write, not only by
a rename. And a PDF that will not open says which of the four reasons it is.
