Put the new workout blocks on the page's reading edge

SubPageShell insets its own heading to the card body edge rather than the
container edge, so a section heading or a meta line rendered flush left sat
16 px to the left of everything above it. The day-context heading, the sport
chips and the count line now take the same responsive inset.
