Module brand 

The startup brand lockup: the three-bar mark, the rpi wordmark, and the Rust crab standing in for the language name.

The layout exists as a module rather than inline in the welcome header for one reason: width must be unambiguous. The lockup this replaced drew a crab above a box containing π. π is East-Asian Ambiguous — width 1 in most locales and width 2 under a CJK locale — so the box borders walked out of alignment depending on the user’s system. The mark here is built from █, which is single-width everywhere; the crab is the only wide glyph, so it is the one thing the layout has to account for, and a test pins its width.

The mark and the wordmark also supply the terminal window/tab title (see window_title), so the tab and the startup screen cannot drift apart.
