Protocol

Test definition

tools/hud/shell_performance.py: control input to changed visible geometry, viewport width 1600px.

Limits

Diagnostic shell, not the launcher's kiosk; budget 50 ms; viewport and instrument changed between the August and September readings, so the series is not strictly like-for-like.
