/**
 * Reader (1.41.0): a PDF read over the page.
 *
 * The dialog fills the viewport -- the page is what is being read, and on a
 * phone there is no room to spare around it -- with a bar above (the title,
 * the original file, Close) and a bar below (the pages and the zoom). Every
 * control is at least 44px square. The page is centred while it fits and
 * scrolls from its edge once it does not (`margin: auto` in a scrolling
 * flex box, never `place-items: center`, which would put the overflow out of
 * reach). Browser pinch-zoom is off inside the page area: the reader's own
 * zoom redraws the page sharp, where a pinch would enlarge its pixels.
 *
 * See `ILM\Components\Support\Reader`.
 *
 * @package ILM\Components
 * @since 1.41.0
