What not to do
Don't set the white K on a bright / high-luminance background — see the contrast table.
Don't add a
<text> element to the mark — keep the glyph as strokes so there's no font dependency.Don't stretch the tile or change its corner radius — keep
rx proportional (≈18%).Don't merge the tagline and slogan into one sentence — noun phrase + action line, kept distinct.
