I skipped this for a bit because I couldn't think of a simple way to
adapt this behavior to a web component + vanilla CSS setting, but then
I thought of CSS variables, and sat down and cranked this out!
I noticed the last row of the species faces required a scroll, I forget
when that happened! But I made some tweaks, most notably widened the
container from the normal 800px, so that on bigger screens everything
lays out and aligns nice, without requiring any scrolling of the face
container!
If something goes wrong, like the site goes down or has an intermittent
error, try a full pageload. That way, we're both retrying, and in a way
that gives the user more control and visibility into what's going on,
and what they can potentially do about it. (e.g. if there's a useful
error message, they will see it!)
Oh right, forgot about this lol!
The specific effect on Impress 2020 where the button label expands is,
kinda hard to implement in normal CSS/JS, and so I'm not in the mood
and I'm settling for the `title` attribute lol
Oh right, I need the error indicator to be part of a container that
also contains the outfit viewer, to appear below it!
I was motivated because I realized I forgot the Customize More button
so now I'm building it lol
The loading indicator *should* fade in after two seconds, to avoid a
flash of a loading indicator when the page loads quickly - but in some
circumstances it wouldn't delay:
1. Visit an item page. (It delays correctly the first time!)
2. Click "Infinite Closet", then click a link to another item page.
3. The loading indicator appears immediately, because this time the
web component JS is already loaded, so the `outfit-layer` elements
enter `:state(loading)` *immediately*. The element starts at
`opacity: 1`, and the delay doesn't matter, because it was never at
anything else.
In this change, we have the `outfit-viewer` web component take on a
`:state(after-first-frame)`, after a `setTimeout(0)` resolves. That
enables the loading state CSS to *never* apply on the first frame, but
then sometimes kick in on the *second* frame, so that the element is
correctly perceived as "transitioning" from hidden to visible, and the
two-second delay will apply.
When I run `bin/deploy:precompile` on the previous version, I get an
error from libsass that `vw` and `vh` are incompatible units. I don't
get this error in development, only when compiling for production.
My inference is:
1. For the production build, Sass is trying to preprocess even non-SASS
files, maybe to help minify them?
2. In Sass, their `min()` existed before CSS's `min()`, so it's
treating it Like That, and returning a reasonable-in-some-cases-but-
not-here error that `min(100vw, 100vh)` can't be *precomputed*.
Anyway, wrapping it in `calc()` isn't a *problem*, and helps the Sass
compiler not try to precompute it, so. Okay!

For static image layers, this was *always* logging that we failed to
send the frame a "pause" message. Which, like, of course!
It makes sense to log the notable circumstance where we send a message
we *expect* to arrive, but the frame isn't loaded yet. But if there's
just no frame, ignore it and don't bother to say so.
We add a new `use_responsive_design` helper, for pages to opt into this
new CSS—mostly just because like… it's *worse* to apply these styles
for pages that don't expect it 😅
And then, I fix up a couple things on the item page (including in the
general items layout) to match!
I'm doing this because the species face picker layout is going to want
some responsive awareness, and I want to be doing that from the start!
Here, I remember the trick I learned when building the outfit viewer:
web components are great for making sure stuff stays initialized well
in a Turbo environment!
The problem was, after submitting the form and getting a new preview
loaded via Turbo, the part where we remove `inert` would get undone.
Additionally, this script only loads *once* per session, so if you
Turbo-nav to a different item then that part of the page never ran.
Instead, we use web components to remove the attributes on mount, then
again if they're ever reapplied by Idiomorph.
We mark the options as `inert` and `aria-hidden` while the JS is still
loading—and if the `noscript` tag tells us it's never coming, it covers
up the picker with a brief explainer!
The basics are working great! There's a few known missing things though:
- Add reasonable noscript behavior
- Disable options where there's no valid appearance
- Lay it out actually _good_, instead of just images dumped there
Adapting what the Impress 2020 UI does, but in Ruby instead!
I feel like this is case is really starting to show the power of doing
this stuff in Rails instead of via an API… we can *really* take
advantage of our models and our handy idioms at all points. This is
just so much less *code* than this feature takes in Node + GraphQL +
React.
Closes#2, after making some tweaks to the PR to fit how JS templating
works here. Thanks @dice!!
I had to move `petThumbnailUrl` out of the closure, because this script
does a cute thing of having separate variable scopes for the separate
areas of the page—but this is used by two of them. Arguably it could
make sense to like, put this all in one larger shared IIFE closure that
wraps both of them, to preserve some of this code's intention of
avoiding adding to the global namespace on this page, but like.
*It's fine.*

Oh right, if the *label* is `:active`, that only applies if we're
clicking it with our mouse. But if the *toggle* is actively, that
applies both to mouse events on the label, and keyboard events on the
checkbox.
Specifically, if a movie layer was the top layer, the `cursor: wait` on
the preview wouldn't show, because the iframe's *contents* would take
priority, and they were using the default cursor.
I thiiiink I've seen the status of a movie `<outfit-layer>` sometimes
be `loading` even when it's clearly already loaded and running. I
haven't been able to track down where and how that happens exactly, so
this is me acting on a hunch: that maybe the
I-would-have-thought-very-unlikely event that the iframe finishes
loading before the `<outfit-layer>` connects with its children maybe
happens more often than one might think!
In this change, we set up the iframe to receive `requestStatus`
messages, which it responds to with the status immediately. And we send
one of these when the `<outfit-layer>` first discovers the iframe.
Fingers crossed!
This doesn't do a good job maintaining state across morphs, but hey
it's Working At All in terms of wiring, and that's good!!
Also need to style up the toggle as a cute button instead of a visible
checkbox and the words "Play/pause"!
This is a nice extra error handler to have, but note that it *won't*
catch the case where the iframe successfully loads but the page returns
a bad status code. In this case, we'll just show the loading state
forever.
Add some unobtrusive white background for contrast, show it when the
Turbo frame is loading too, add a spinner cursor, and fix a silliness
of how we put the `position: absolute` stuff into the component-y part
of the hanger spinner instead of this specific use case lol oops!
This doesn't actually really matter, because this doesn't actually get
used in the app right now? But I figure, hey it's not hard to maintain,
let's just do it for consistency!
The most notable thing here is that we keep the movie iframes running!
So if you're trying different pets for an animated item, the animation
keeps going while the new pet layers load alongside it.
This is also nice for like, the species/color picker form, so we're not
taking away input elements from people who depend on e.g. keyboard
focus.
Not using this on the item page preview yet, but we will!
I like this approach over e.g. a web component specifically for the
sandboxing: while I don't exactly *distrust* JS that we're loading from
Neopets.com, I don't like the idea of *any* part of the site that
executes arbitrary JS unsafely at runtime, even if we theoretically
trust where it theoretically came from. I don't want any failure
upstream to have effects on us!
I copied basically all of the JS from a related project
`impress-media-server` that I had spun up at one point, to investigate
similar embed techniques. Easy peasy drop-in-squeezy!
Oh right okay, attributes like `status="loading"` are more of an API
for the caller, whereas the internal state API is where you wanna put
things that are meant to be used in CSS selectors and stuff.
Instead of doing all this listening to Turbo events etc to know when
outfit layers might have changed, making it a custom element and wiring
in the behavior to its actual lifecycle makes it always Just Work!
The UI for it is just basic for my own testing rn: it sets the preview
background to gray while loading, then back to white when done!
This uses the new CSS `:has()` selector: we have JS manage the loading
state on each layer, then the container just restyles itself based on
whether any currently-loading layers are present.
This is a cute thing that I think sets us up for other stuff down the
line: move more of the outfit appearance logic into the `Outfit` class!
Now, we set up the item page with a temporary instance of `Outfit`,
then ask for its `visible_layers`.
Still missing restricted-zones logic and such, that's next!
