+"""Draw the CoreDesktop wordmark in the construction of the Federated wordmark.
+
+Measured from Federated's logo.png (775x129): every glyph sits in a 58x57 box
+starting at y=55, strokes are 13px, outer corners ~16px radius. Glyphs here are
+centerline paths stroked at 13px with 9.5px arcs (16px outside, ~3px inside).
