Now that we have this helper, we no longer need these stylesheets to
include a `body.controller-action` wrapper to scope all the styles!
Someday we should convert more of our stylesheets to this format,
instead of slamming them all into `application.sass` like we do now.
Ah, well!
First one, Turbo reasonably yelled at us in the JS console that we
should put its script tag in the `head` rather than the `body`, because
it re-executes scripts in the `body` and we don't want to spin up Turbo
multiple times!
I also removed some scripts that aren't relevant anymore, fixed a bug
in `outfits/new.js` where failing to load a donation pet would cause
the preview thing to not work when you type (I think this might've
already been an issue?), reworked `item_header.js` to just run once in
the `head`, and split scripts into `:javascripts` (run once in `head`)
vs `:javascripts_body` (run every page load in `body`).
Mostly this is just me testing out what it would look like to
modularize the app more… I've noticed that some concerns, like
fundraising, are just not relevant to most of the app, and being able
to lock them away inside subfolders feels like it'll help tidy up
long folder lists.
Notably, I haven't touched the models case yet, because I worry that
might be a bit more complex, whereas everything else seems pretty
well-isolated? We'll try it out!
