Clamping the window to now made the past unreachable — you could not see when
a running event began. Rendering from the earliest start instead buried today
off-screen, which is what the clamp was fixing.
The window now covers both and the container opens scrolled to today, so the
default view is unchanged and history is a scroll away. It reaches a week
past the oldest running event, so the range stays bounded by what is actually
live. Nothing is clipped at the left edge any more.
