# The native Slint front-end (slint-frontend/ in the app repo). Installed alongside the
# web UI, not instead of it: both talk to the same backend, so the two can be compared
# on the same screen.

# Built on the device rather than on the control machine, which is the opposite of what
# pi_musicmouse does for the web front-end - and for a reason. The Pis run 32-bit armhf
# Raspbian on a 64-bit kernel, so the target is armv7-unknown-linux-gnueabihf. Cross
# compiling to it needs a sysroot, and the device has no -dev packages to build one
# from, so the choice is between reconstructing one from the Debian archive (and
# owning a glibc-version skew risk forever) or spending the device's own CPU once.
# A rebuild only happens when the commit changes - see the stamp below.

# winit + FemtoVG + the software renderer. Deliberately not Skia: rust-skia ships no

# that were actually rendered, which is the honest measure for a UI that idles.
