On a phone the Back button left the page under an open menu, sheet or dialog. An open overlay now says so (new
IDOverlayHost, cascaded by MainLayout; OverlayService keeps them newest last): DModal and DDropdown through the
cascade, so the D components stay free of app services, and the nav menu, PhoneSheet and the full-screen globe through
the service. MainLayout's location-changing handler lets Back close the newest overlay instead of leaving the page; a
link followed or the app's own navigation (signing out after its question, say) closes them all and goes on. Blazor
can't tell Back from the app's navigation, so a capture-phase popstate listener in main.js marks Back
(AppStatusService.TookBack). No history entries are pushed. Phone flow: Back closes the menu, a card's More sheet, the
composer and the full-screen globe one after another without leaving the feed, and with nothing open goes back.

On a phone the composer opened at the top of the feed whether or not the feed was scrolled there, and a reply, quote
or edit opened inside its card's 228px column. New PhoneSheet shows them as a sheet from the bottom of the screen below
md, over a dimmed page, with a heading and a close button (a tap outside or Escape closes it too); from md they stay in
place as before. On a phone a new post starts from a round button under the thumb (the feed keeps room for it at the
bottom), and the tabs' Post button shows from md. Opening the composer scrolls the feed to its top, and the composer's
words take the focus (DTextarea.Element). Picking a suggested mention or hashtag keeps the focus, and the phone's
keyboard, in the words (DButton.KeepFocus, and the words are focused again). The character count sits under the words
instead of over their last line, and the visibility menu names each choice.
