What the screen shows before you Start

There are no onboarding overlays in the centre of the screen — the inline Set Grade bar at the bottom is the whole "no grade yet" state.

• While grading is idle, the Set Grade bar is always present at the bottom of the map. The grade chip in the top stats bar stays grey until parameters are applied, then shows the grade and direction in color.
• Once Start anchors a 0+00 reference and grading is active, the bar hides and the chevrons + profile chart take over the centre of the screen.
