Recommended variant from gosentry-logo.html: Space Grotesk SemiBold with an amber "G", a clock-dial "o" (ring + hands), and petrol "Sentry". Ships self-contained SVGs (glyphs outlined to paths, no font dependency) in light/dark/mono plus transparent PNGs at 256-2048px, with a README and the gen_logo.py/raster.py generators for reproducibility.
