body is a grid of topbar / main / status / player, and nothing in the page
accounted for a display's own intrusions. Mobile Safari hides that by
insetting the layout viewport to the safe area, so the site was fine in a
browser -- but a full-screen shell, the native app or the site added to an
iOS home screen, hands the page the whole display, and the last row landed
under the home indicator with its seek bar and times half cut off.
viewport-fit=cover asks for the whole screen deliberately, and the bars
along the edges now pay for the insets in padding: the bottom for the
indicator, left and right for the notch in landscape. A browser with its
own chrome reports nought and nothing moves.
The padding has to be longhand, and there is a comment saying so, because
the minifier drops the space between a calc() and the value after it in a
shorthand -- padding:7px calc(12px + var(--safe-r))7px ... -- and a browser
then throws the whole declaration away. The bars lost all their padding,
which moved the item list far enough that the pull-to-refresh browser test
stopped finding it; nothing reported an error, and the page still loaded.
buildStyle now fails the build on a calc() run into its neighbour rather
than trusting it.
