Consider a Intro/Basics version (one scene per screen)

Chemistry educators at the recent Quantum Summer Working Group had some feedback on Quantum Wave Interference worth considering for a future release. They loved the Experiment Screen, and would likely only use that screen. They had some hesitation about including all four particle types so prominently on the screen, worried it would give away that everything undergoes interference. There was also some talk of adding a "sand gun" (fast enough that gravity doesn't matter) as a classical point of comparison.

One possibility would be a QWI Intro/Basics (like Waves Intro) where each screen has a single particle type.

We've emailed the educators to follow up about:

• Whether QWI Intro would actually solve their concern, and if it'd become their go-to version
• How much they care about having a classical comparison like the sand gun

If QWI Intro is genuinely wanted, we'd move forward with building it at a future date (no changes to the current QWI release plans). If there's real interest in the sand gun too, we'd look into that once QWI Intro is prioritized.

No files, tests, or entry points are named. First review the educator follow-up about a QWI Intro/Basics version and a classical sand-gun comparison; the work is ready only after the desired scope is confirmed and prioritized for a future release.
