The Plugin / GitHub / Settings labels open with siDeepseek, siGithub,
and the harness's IconSettingsOutline14 gear, riding currentColor at the
label's baseline. simple-icons is a dev-only dependency pinned to the
harness ui-primitives' own 16.31.0 and tree-shakes into lib/client.js as
exactly the two mark paths, so no runtime dependency is added and the
marks are identical to the harness's own SiteGlyph artwork.
