This regression was introduced by commit 3902 in June.
Making this commit clean took the last 4 commits of reorganizing.

It's always been ugly that I referred to a later layer/feature in a
label name.

We never ended up using this, and all it has provided is a hole in the
type system.
Java's lesson is that globals are not essential. Any program that uses
globals can be rewritten to do without them. Just thread a world object
through the program, saving global state in it, and extracting relevant
bits of global state to pass into functions lower down the call chain.
Thanks Andrew Owen for the conversation that led me to focus on this
issue.

Instead of setup() and teardown() we'll just use a reset() function from
now on, which will bring the machine back to a good state before each
test or run, and also before exit (to avoid memory leaks).

I'm in the process of making it more self-contained so I can use it in
another project.

Narrow the scope of implicit type conversions. Now only numbers can be
freely converted to from other scalars (booleans, characters). We want
in particular to make this an error:
x:character <- new [abc]

Yet another regression, this time cascading from commit 3953. My
scenario wasn't actually testing what I thought it was testing.

Expand the steps in `update_html` and try to process each set of files
separately so we can see commonality.
The eventual goal is a script that can selectively process a subset of
files. But this is a good first step: I can at least easily comment out
different subsets.

Don't refresh entire sandbox side when toggling the expected result for
a single sandbox.

Don't unnecessarily write sandboxes to disk on F4.
This seems to save almost 20% time when processing a large lesson
directory with 36 sandboxes.

Improvement on fix 3957: rather than put a band-aid over a slow
operation, eliminate the slowdown entirely.
In this case it turns out we're unnecessarily saving files to disk when
they could never be modified. Are we doing this on F4 as well?!

Marking sandbox responses as expected can take a long time if there are
many sandboxes. Indicate when a click is being worked on.

Move a scenario which is after commit 3954 applicable to both editors,
not just the recipe side.

As a blanket rule, down-arrow now stops scrolling once the bottom margin
comes on screen.
Now that we have page-wise scrolling with ctrl-f/b and line-wise
scrolling with ctrl-s/x, we don't need to conflate scroll positioning
with the arrow keys. And as a result, early students no longer have to
struggle with accidentally scrolling part of the sandbox off the screen
when there's tons of empty space available.
`move-to-next-line` is still super messy and will need further
rethinking, but this commit simplifies the codebase as a whole by
eliminating a couple of historical accidents:
a) We only introduced scrolling past the bottom of the screen to allow
more sandboxes to come into view before we had scrolling for the
sandbox side.
b) We undid scrolling past the bottom in just the recipe side to allow
errors to come into view.
Since these historical details are now irrelevant, we no longer need
separate logic for the recipe and sandbox sides, and we don't need to
keep track of the recipe-bottom separate from the bottom margin of
arbitrary editors.
