Are the @2x and @3x graphics doing anything?
The proxy/static/assets directory contains @2x and @3x hi-res versions of the status-off, status-on, and status-running icons.
But the @2x and @3x filenames are not referred to anywhere. I suspect they were intended to be included in a resolution @media query, but they are not.
Rather than adding the @media queries, could we just delete all the PNGs and use only SVGs in the popup? In the toolbar icon we cannot use SVG, but those graphics are separate from the popup ones.
To upload designs, you'll need to enable LFS and have admin enable hashed storage. More information
