2ro 2d2bf326b3 Goblin Build 116
Floonet scoped Nym exit on the money-path relay (dial a relay operator's
co-located exit over a MixnetStream, TLS end to end, no public DNS; anchor +
fallback, never pin-only), NIP-44 v3 gift wraps (G4), mix-DNS, localization,
GUI polish. Verified end to end: two wallets complete a real gift-wrapped Grin
payment over relay.goblin.st, finalized + posted on mainnet.

# Regenerate EVERY platform's app icon from two canonical sources:
# img/goblin-icon.png the gradient app icon (yellow gradient + black mascot)
# img/goblin-mark-black.svg the black mascot mark, vector, transparent bg
# (mirror of site/assets/goblin-mark-black.svg)
#
# Square icons (desktop window, Linux AppImage, Android launcher, Windows .ico,
# macOS .icns) come from the gradient PNG. The Android *adaptive* foreground is
# the black mascot on transparency, composited by the OS over the yellow
# background color (res/values/ic_launcher_background.xml = #FFD60A) — which
# reproduces the gradient icon's look.
#
# Requires ImageMagick (magick) and python3 (for the .icns container).
