Run heavy loads while the marker is inside the window.

The chart is not decoration. It shows time passing, the useful window, and why the recommendation changes when you scrub.

Time moves

The now marker creeps. Nothing else fidgets.

Scrub feel

Peak snap

Near the load window, the scrubber gently locks to useful hours.

Motion thesis: move only what explains the rig. The solar curve draws once to say "forecast loaded." The now marker creeps to say "time is passing." The sun rides the production curve to say "your rig is alive right now." The scrub snaps only inside the run-load window to say "this is the useful range." Reduced mode keeps the same layout, removes ambient animation, and still allows scrubbing.
