report(redesign): new gauges, score scale, category headers, variables
Design reference: https://yuinchien.github.io/sandbox/lighthouse/

A possibly exhaustive list of what I did:

* Gauges have a light background.
* Separator removed between normal categories and the PWA.
* Gauges are bigger.
* Line separator between sections.
* Score scale is centered, given a border, and order reversed.
* Previous sticky heady behavior disabled for now - new sticky header will be done in a follow up PR.
* Category description is centered and larger.
* Various new variables defining font sizes, colors, spacings, etc.

See: https://lh-pr-report-redesign.surge.sh/1

#8185

exterkamp: Love this 😍 

I have nits but I realize that this is only step 1.  From a _gauges only_ perspective: LGTM.

Can we move the header stuff inside the margin?

This is the view I get from scrolling once.  I don't know if it is like that for all screens, but on mine it cuts off (see blue circle).  Also the categories float away from the divider (red arrow) it feels a little weird when I scroll.

This is the height that the categories jump to, it'd be more natural if the gauge was at the top if possible so that there isnt any info above.

And the dividers between categories should be full width or at least wider than they are, the categories seem to run together to me rn.


patrickhulce: Woohoo awesome stuff already!! Excellent!!! 😍 

A few nit differences I noticed from the design:

- Same as Shane, "the categories float away from the divider (red arrow) it feels a little weird when I scroll."
- Score legend isn't rounded
- Score legend doesn't have enough margin with the lower divider
![image](https://user-images.githubusercontent.com/2301202/55889729-24507800-5b77-11e9-9ec5-97a8ddd189cf.png)

- Section score gauge is 120px in design but 106px in report (the container is 120 in the report, but the circle ends up being quite a bit smaller for some reason)
- Header score gauges are 90px in design but 85px in report
- Section header text is 28px in design but 20px in report
- Section header text for "Performance" is missing margin between the header and the metrics
- Section header description (for a11y and SEO) is missing margin between header and the description

Hoten: Thanks for the detailed bullets. I went through each, and if it took longer than 10 minutes to make progress I skipped for now.

I can't figure out how to remove that, and I don't know enough to know if removing it would be going against the grain in terms of the follow up sticky work.

If you mess with the viewport of the design reference, it goes from rounded -> square (and then gets stuck even after restoring viewport? hmm). @yuinchien is the score scale supposed to always be rounded, or rounded in desktop & squared in mobile?

Looks the same to me.

this is hard for me. idk why. maybe because the previous styles have the svg positioned normally & the percentage/ absolute, but the design reference does it the other way, which really messes with my tried-and-true "copy and paste and hammer" css skills.

@Hoten the score scale should have 100% rounded corner consistently across screen sizes. 
patrickhulce: > Looks the same to me.

Hm it's definitely rendering the arcs smaller on my machine. The stroke width is also 1px larger in the report than the design which probably contributes to why it visually feels smaller even if the difference is only 6px.

patrickhulce: lookin' real good my friend! who even needs 2 weeks psh 😎 
Hoten: ah, I needed to change the radius.

See: https://lh-pr-report-redesign.surge.sh/3
exterkamp: Just a nit for the future and possibly with that _NOW_ stuff @paulirish: can we make these examples with a site that doesn't do so well on every category and audit like example.com?  Maybe something more like amazon or theverge or apple?  So there is some more variety in the perf section and looks a little more realistic?
Hoten: See: https://lh-pr-report-redesign.surge.sh/4
paulirish: >  can we make these examples with a site that doesn't do so well on every category and audit like example.com

SG. I have 5 sites worth of artifacts locally that I use for this purpose. i can incorporate that into #8159 
Hoten: I know @paulirish is working on the sticky header so I suggest leaving the weird sticky behavior. push this to master? or nah?
patrickhulce: @Hoten I know my comments on the code itself weren't big or anything, but an explanation to satisfy my curiosity would be nice before a merge :)
Hoten: doh! I missed all the comments.
Hoten: nah i'd say the closest is 🌡
