Fix trackball camera by weaving through EngineStream (#6760)

* Fix trackball camera by weaving through EngineStream

Fixes #6472. Just a missing setting moved in #5312, which wasn't caught
because testing that the orbit maneuver is actually performing a
"trackball-like" movement is nonexistent. I don't know how to test that
reliably, but typing this object provides the red squiggles to reveal
the missing property.

* Update src/components/EngineStream.tsx

 ### Rust tests
 
-**Dependencies**
+Prepare these system dependencies:
 
-- `KITTYCAD_API_TOKEN`
-- `cargo-nextest`
-- `just`
+- Set `$KITTYCAD_API_TOKEN` from https://dev.zoo.dev/account/api-tokens
+- Install `just` following [these instructions](https://just.systems/man/en/packages.html)
 
-#### Setting KITTYCAD_API_TOKEN
-
-Use the production zoo.dev token, set this environment variable before running the tests
-
-#### Installing cargonextest
+then run tests that target the KCL language:
 
 ```
-cd rust
-cargo search cargo-nextest
-cargo install cargo-nextest
+npm run test:rust
 ```
 
-#### just
-
-install [`just`](https://github.com/casey/just?tab=readme-ov-file#pre-built-binaries)
-
-#### Running the tests
-
-```bash
-# With just
-# Make sure KITTYCAD_API_TOKEN=<prod zoo.dev token> is set
-# Make sure you installed cargo-nextest
-# Make sure you installed just
-cd rust
-just test
-```
-
-```bash
-# Without just
-# Make sure KITTYCAD_API_TOKEN=<prod zoo.dev token> is set
-# Make sure you installed cargo-nextest
-cd rust
-export RUST_BRACKTRACE="full" && cargo nextest run --workspace --test-threads=1
-```
-
-Where `XXX` is an API token from the production engine (NOT the dev environment).
-
-We recommend using [nextest](https://nexte.st/) to run the Rust tests (its faster and is used in CI). Once installed, run the tests using
-
-```
-cd rust
-KITTYCAD_API_TOKEN=XXX cargo run nextest
-```
-
-### Mapping CI CD jobs to local commands
-
-When you see the CI CD fail on jobs you may wonder three things
-
-- Do I have a bug in my code?
-- Is the test flaky?
-- Is there a bug in `main`?
-
-To answer these questions the following commands will give you confidence to locate the issue.
-
-#### Static Analysis
-
-Part of the CI CD pipeline performs static analysis on the code. Use the following commands to mimic the CI CD jobs.
-
-The following set of commands should get us closer to one and done commands to instantly retest issues.
-
-```
-npm run test-setup
-```
-
-> Gotcha, are packages up to date and is the wasm built?
-
-```
-npm run tsc
-npm run fmt:check
-npm run lint
-npm run test:unit:local

-
-#### E2E Tests
-
-**Playwright Electron**
-
-These E2E tests run in electron. There are tests that are skipped if they are ran in a windows, linux, or macos environment. We can use playwright tags to implement test skipping.
-
-```
-npm run test:playwright:electron:local
-npm run test:playwright:electron:windows:local
-npm run test:playwright:electron:macos:local
-npm run test:playwright:electron:ubuntu:local
-```
-
-> Why does it say local? The CI CD commands that run in the pipeline cannot be ran locally. A single command will not properly setup the testing environment locally.
-
-#### Some notes on CI
-
-The tests are broken into snapshot tests and non-snapshot tests, and they run in that order, they automatically commit new snap shots, so if you see an image commit check it was an intended change. If we have non-determinism in the snapshots such that they are always committing new images, hopefully this annoyance makes us fix them asap, if you notice this happening let Kurt know. But for the odd occasion `git reset --hard HEAD~ && git push -f` is your friend.
-
-How to interpret failing playwright tests?
-If your tests fail, click through to the action and see that the tests failed on a line that includes `await page.getByTestId('loading').waitFor({ state: 'detached' })`, this means the test fail because the stream never started. It's you choice if you want to re-run the test, or ignore the failure.
-
-We run on ubuntu and macos, because safari doesn't work on linux because of the dreaded "no RTCPeerConnection variable" error. But linux runs first and then macos for the same reason that we limit the number of parallel tests to 1 because we limit stream connections per user, so tests would start failing we if let them run together.
-
-If something fails on CI you can download the artifact, unzip it and then open `playwright-report/data/<UUID>.zip` with https://trace.playwright.dev/ to see what happened.
-
-#### Getting started writing a playwright test in our app
-
-Besides following the instructions above and using the playwright docs, our app is weird because of the whole stream thing, which means our testing is weird. Because we've just figured out this stuff and therefore docs might go stale quick here's a 15min vid/tutorial

+
+`KCL` allows splitting code up into multiple files.  Each file is somewhat
+isolated from other files as a separate module.
+
+When you define a function, you can use `export` before it to make it available
+to other modules.
+
+```kcl
+// util.kcl
+export fn increment(@x) {
+  return x + 1
+}
+```
+
+Other files in the project can now import functions that have been exported.
+This makes them available to use in another file.
+
+```norun
+// main.kcl
+import increment from "util.kcl"
+
+answer = increment(41)
+```
+
+Imported files _must_ be in the same project so that units are uniform across
+modules. This means that it must be in the same directory.
+
+Import statements must be at the top-level of a file. It is not allowed to have
+an `import` statement inside a function or in the body of an if‑else.
+
+Multiple functions can be exported in a file.
+
+```kcl
+// util.kcl
+export fn increment(@x) {
+  return x + 1
+}
+
+export fn decrement(@x) {
+  return x - 1
+}
+```
+
+When importing, you can import multiple functions at once.
+
+```norun
+import increment, decrement from "util.kcl"
+```
+
+Imported symbols can be renamed for convenience or to avoid name collisions.
+
+```norun
+import increment as inc, decrement as dec from "util.kcl"
+```
+
+---
+
+## Functions vs `clone`
+
+There are two common patterns for re‑using geometry:
+
+1. **Wrap the construction in a function** – flexible and fully parametric.
+2. **Duplicate an existing object with `clone`** – lightning‑fast, but an exact
+   duplicate.
+
+### Parametric function example
+
+```kcl
+fn cube(center) {
+  return startSketchOn(XY)
+    |> startProfile(at = [center[0] - 10, center[1] - 10])
+    |> line(endAbsolute = [center[0] + 10, center[1] - 10])
+    |> line(endAbsolute = [center[0] + 10, center[1] + 10])
+    |> line(endAbsolute = [center[0] - 10, center[1] + 10])
+    |> close()
+    |> extrude(length = 10)
+}
+
+myCube = cube(center = [0, 0])
+```
+
+*Pros*
+- Any argument can be a parameter – size, position, appearance, etc.
+- Works great inside loops, arrays, or optimisation sweeps.
+
+*Cons*
+- Every invocation rebuilds the entire feature tree.
+- **Slower** than a straight duplicate – each call is its own render job.
+
+### `clone` example
+
+```kcl
+sketch001 = startSketchOn(-XZ)
+  |> circle(center = [0, 0], radius = 10)
+  |> extrude(length = 5) 
+  |> appearance(color = "#ff0000", metalness = 90, roughness = 90)
+
+sketch002 = clone(sketch001)  // ✓ instant copy
+```
+
+*Pros*
+- Roughly an O(1) operation – we just duplicate the underlying engine handle.
+- Perfect when you need ten identical bolts or two copies of the same imported STEP file.
+
+*Cons*
+- **Not parametric** – the clone is exactly the same shape as the source.
+- If you need to tweak dimensions per‑instance, you’re back to a function.
+
+> **Rule of thumb** – Reach for `clone` when the geometry is already what you want. Reach for a function when you need customisation.
+
+---
+
+## Module‑level parallelism
+
+Under the hood, the Design Studio runs **every module in parallel** where it can. This means:
+
+- The top‑level code of `foo.kcl`, `bar.kcl`, and `baz.kcl` all start executing immediately and concurrently.
+- Imports that read foreign files (STEP/OBJ/…) overlap their I/O and background render.
+- CPU‑bound calculations in separate modules get their own worker threads.
+
+### Why modules beat one‑big‑file
+
+If you shoe‑horn everything into `main.kcl`, each statement runs sequentially:
+
+```norun
+import "big.step" as gizmo  // blocks main while reading
+
+gizmo |> translate(x=50)    // blocks again while waiting for render
+```
+
+Split `gizmo` into its own file and the read/render can overlap whatever else `main.kcl` is doing.
+
+```norun
+// gizmo.kcl                   (worker A)
+import "big.step"
+
+// main.kcl                    (worker B)
+import "gizmo.kcl" as gizmo   // non‑blocking
+
+// ... other setup ...
+
+gizmo |> translate(x=50)      // only blocks here
+```
+
+### Gotcha: defining but **not** calling functions
+
+Defining a function inside a module is instantaneous – we just record the byte‑code. The heavy lifting happens when the function is **called**. So:
+
+```norun
+// util.kcl
+export fn makeBolt(size) { /* … expensive CAD … */ }
+```
+
+If `main.kcl` waits until the very end to call `makeBolt`, *none* of that work was parallelised – you’ve pushed the cost back onto the serial tail of your script.
+
+**Better:** call it early or move the invocation into another module.
+
+```norun
+// bolt_instance.kcl
+import makeBolt from "util.kcl"
+bolt = makeBolt(5)  // executed in parallel
+bolt
+```
+
+Now `main.kcl` can `import "bolt_instance.kcl" as bolt` and get the result that was rendered while it was busy doing other things.
+
+---
+
+## Whole module import
+
+You can also import the whole module. This is useful if you want to use the
+result of a module as a variable, like a part.
+
+```norun
+import "tests/inputs/cube.kcl" as cube
+cube
+  |> translate(x=10)
+```
+
+This imports the whole module and makes it available as `cube`. You can then
+use it like any other object. The `cube` variable is now a reference to the
+result of the module. This means that if you change the module, the `cube`
+variable will change as well.
+
+In `cube.kcl`, you cannot have multiple objects. It has to be a single part. If
+you have multiple objects, you will get an error. This is because the module is
+expected to return a single object that can be used as a variable.
+
+The last expression or variable definition becomes the module's return value.
+The module is expected to return a single object that can be used as a variable
+by whatever imports it.
+
+So for example, this is allowed:
+
+```norun
+... a bunch of code to create cube and cube2 ...
+
+myUnion = union([cube, cube2])
+```
+
+You can also do this:
+
+```norun
+... a bunch of code to create cube and cube2 ...
+
+union([cube, cube2])
+```
+
+Either way, the last line will return the union of the two objects.
+
+Or what you could do instead is:
+
+```norun
+... a bunch of code to create cube and cube2 ...
+
+myUnion = union([cube, cube2])
+myUnion
+```
+
+This will assign the union of the two objects to a variable, and then return it
+on the last statement. It's simply another way of doing the same thing.
+
+The final statement is what's important because it's the return value of the
+entire module. The module is expected to return a single object that can be used
+as a variable by the file that imports it.
+
+---
+
+## Multiple instances of the same import
+
+Whether you are importing a file from another CAD system or a KCL file, that
+file represents object(s) in memory. If you import the same file multiple times,
+it will only be rendered once.
+
+If you want to have multiple instances of the same object, you can use the
+[`clone`](/docs/kcl/clone) function. This will render a new instance of the object in memory.
+
+```norun
+import cube from "tests/inputs/cube.kcl"
+
+cube  
+  |> translate(x=10)
+clone(cube)
+  |> translate(x=20)
+```
+
+In the sample above, the `cube` object is imported from a KCL file. The first
+instance is translated 10 units in the x direction. The second instance is
+cloned and translated 20 units in the x direction. The two instances are now
+separate objects in memory, and can be manipulated independently.
+
+Here is an example with a file from another CAD system:
+
+```kcl
+import "tests/inputs/cube.step" as cube
+
+cube
+  |> translate(x=10)
+clone(cube)
+  |> translate(x=20)
+```
+
+---
+
+## Importing files from other CAD systems
+
+`import` can also be used to import files from other CAD systems. The format of the statement is the
+same as for KCL files. You can only import the whole file, not items from it. E.g.,
+
+```norun
+import "tests/inputs/cube.obj"
+
+// Use `cube` just like a KCL object.
+```
+
+```kcl
+import "tests/inputs/cube.sldprt" as cube
+
+// Use `cube` just like a KCL object.
+```
+
+For formats lacking unit data (such as STL, OBJ, or PLY files), the default
+unit of measurement is millimeters. Alternatively you may specify the unit
+by using an attribute. Likewise, you can also specify a coordinate system. E.g.,
+
+```kcl
+@(lengthUnit = ft, coords = opengl)
+import "tests/inputs/cube.obj"
+```
+
+When importing a GLTF file, the bin file will be imported as well.
+
+Import paths are relative to the current project directory. Imports currently only work when
+using the native Design Studio, not in the browser.
+
+### Supported values
+
+File formats: `fbx`, `gltf`/`glb`, `obj`+, `ply`+, `sldprt`, `step`/`stp`, `stl`+. (Those marked with a
+'+' support customising the length unit and coordinate system).
+
+Length units: `mm` (the default), `cm`, `m`, `inch`, `ft`, `yd`.
+
+Coordinate systems:
+
+- `zoo` (the default), forward: -Y, up: +Z, handedness: right
+- `opengl`, forward: +Z, up: +Y, handedness: right
+- `vulkan`, forward: +Z, up: -Y, handedness: left
+
+---
+
+## Performance deep‑dive for foreign‑file imports
+
+Parallelized foreign‑file imports now let you overlap file reads, initialization,
+and rendering. To maximize throughput, you need to understand the three distinct
+stages—reading, initializing (background render start), and invocation (blocking)
+—and structure your code to defer blocking operations until the end.
+
+### Foreign import execution stages
+
+1. **Import (Read / Initialization) Stage**
+   ```kcl
+   import "tests/inputs/cube.step" as cube
+   ```
+   - Reads the file from disk and makes its API available.
+   - Starts engine rendering but **does not block** your script.
+   - This kick‑starts the render pipeline while you keep executing other code.
+
+2. **Invocation (Blocking) Stage**
+   ```kcl
+   import "tests/inputs/cube.step" as cube
+
+   cube
+     |> translate(z=10) // ← blocks here only
+   ```
+   - Any method call (e.g., `translate`, `scale`, `rotate`) waits for the background render to finish before applying transformations.
+
+### Best practices
+
+#### 1. Defer blocking calls
+
+```kcl
+import "tests/inputs/cube.step" as cube     // 1) Read / Background render starts
+
+
+// --- perform other operations and calculations here ---
+
+
+cube
+  |> translate(z=10)                        // 2) Blocks only here
+```
+
+#### 2. Split heavy work into separate modules
+
+Place computationally expensive or IO‑heavy work into its own module so it can render in parallel while `main.kcl` continues.
+
+#### Future improvements
+
+Upcoming releases will auto‑analyse dependencies and only block when truly necessary. Until then, explicit deferral will give you the best performance.
