It measures 142.6 × 120 mm and has 2 copper layers, 1.6 mm thick.
124 parts, built around the 1N4148W and SK6812MINI-E. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
From the jimmerricks/ursula repository on GitHub, at the commit this page was made from: the board is pcb/ursula.kicad_pcb and its schematic pcb/ursula.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Its repository states no licence, so its author keeps all rights: ask jimmerricks before reusing the design.
