#98971a was gruvbox's faded green, picked from the palette rather than from
the mark. The island tile is #8ec07c - sampled from the wordmark itself, so
the badge and the logo now agree. Dark text on it is 7.0:1 rather than 4.8:1,
which is a gain as well.
One SVG, gruvbox-coloured to match the wordmark, plus the three ways to use
it and the trade each makes. Copying the file is recommended over shields.io:
a badge in someone else's README should not make every reader of it fetch
from a third party.
Notes the two forge fields that reach further than a README does - topics
above all, since those are searchable across a forge and a badge is not.
