Use CSS from Fluid by default

[rolyp]

The Methane example works ok as a “standalone” figure but has several problems in https://explorable-viz.github.io/fluid-example-ipcc-ar6-01/ when viewed in Firefox. The culprit is styles.css, which this example provides its own copy of, rather than picking up the version provided by fluid (in particular it still uses zoom, which isn’t supported in Firefox).

• Pick up styles.css and other CSS from fluid submodule
• Delete local CSS files except for minimal overrides required for article

For now it should be possible to fix this (mostly/entirely) by deleting the zoom property from .double-size in styles.css. If some resizing is required the approach taken by styles.css in the Fluid submodule can be used. The longer-term fix I think is to pick up styles.css from Fluid and only override locally when specifically needed.

Works in Firefox now (https://explorable-viz.github.io/fluid-example-ipcc-ar6-01/) but I have to remove the code for .double-size because that was breaking the centring of the plot and wouldn’t show the data sidebar.

Anyway, it works!

This is addressed by explorable-viz/fluid#924, but won’t close this until we come back to https://explorable-viz.github.io/fluid-example-ipcc-ar6-01/.
