v0.4.8 First build that runs on a Mac other than the one that made it. The bundled interpreter pointed at the build machine's pyenv, its _ssl at Homebrew's OpenSSL and potrace at a Cellar path, so the app could not start its engine anywhere else. Every bundled binary now resolves inside the app, and the build fails if one does not. Semantic naming works for SVG sheets: icons exported from vector sources carry their artwork in the alpha channel, and the model was being shown a black square, answering heart for all 47 icons of a sheet. Also: the engine no longer invalidates the app's signature by writing bytecode into the bundle, Start Server actually starts a server that outlives the command, per-icon naming outcomes and engine warnings are visible in the UI, and a run can be stopped.
