The wordmark I put there was not what the author expected: the brand is "4", a
green waveform of stacked lenses, then "3A".
Only the waveform is SVG. The digits stay HTML text so they keep the sidebar's
own typeface at any theme or zoom — an SVG <text> would pick its own font and
drift from the menu around it. Seven ellipses, tallest in the middle, match the
shape of the mark.
Still drawn rather than fetched: an image off the web has no verifiable
provenance, and this stays one small component to swap if the official SVG is
preferred.
