The Settings window loads the same page as project windows, so it showed the
launch splash with the logo. It now shows only the bar, after 400 ms.
The bar's sliding animation was switched off under reduced motion, leaving a
static 40% fill. It is now a fake progress that eases towards ~90% and fills
to 100% before the splash fades out.

Project windows are created in setup with the saved theme's frame colour, and the splash covers the first render while the launch project opens, so a window no longer flashes white or the Welcome screen. Single-instance is now release-only so a dev build can run beside an installed release.
