- legacy Style and ThemePalette removed
- moved and deduplicated font definitions into `Theme` (unrelated to a
color palette)
- `Style.current.foo` -> `Theme.foo`
- `Style.current.fooColor` -> `Theme.palette.fooColor`
- upgrade the imports to 5.15
- removed some mode dead components
Fixes#16514
- wrap everything we can in AppMain with a (async) Loader
- do not access globals w/o a proper store
- drop some dead code
Although I wasn't able to completely fix the bug, the ~50% improvement in
startup time is still worth trying imho. On my machine, the startup time
went down from ~7s to under 4s.
