**Inspecting files for build** I need to build something and check if three files exist first. I'll implement one index, focusing on custom orbit controls since there are only three. It should be polished, and I'm imagining the trajectory drawing over time with glowing, layered lines and possibly some particles for effect. The user interface doesn't require external elements, so I'll take a closer look at what I have on hand. Let’s dive into the details.

**Assessing potential issues** I'm thinking about whether the browser might be unavailable, which could affect the Replay button. If it's showing complete after playing, it shouldn’t reset and must handle state correctly. The Pause label needs to change the play functionality based on visibility; if conditions aren’t met, it should toggle instead. I also need to ensure that the halo is drawn correctly within the same geometric range. Maybe I can inspect the syntax using Node for extraction? I'll check everything with both Python and Node.

MEASUREMENTS
Raw readings from the capture, not a verdict — the grade above is the only judgement. Percentages are how much of the screen changed; the measure under-reports sparse motion on a dark background.
