- assets/icon.png (generated by scripts/make-icon.py) + icon.iconset (scripts/gen-iconset.sh); electrobun compiles it to AppIcon.icns - branding.icon points at the iconset - README: features, stack, dev/build, rebranding, plaintext-password warning, shortcuts, v1 scope - verified: full production build (ng build + electrobun build) produces a launchable BunSCP.app that boots standalone from views://app Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
