Em dashes are a common AI-writing tell; swap them (and en dashes) for plain
hyphens across the README and all KDoc/comment prose so the repo reads as
hand-authored. Byte-level replace of U+2014/U+2013 -> '-'; arrows and the
ellipsis are left untouched.
The two functional em dashes are intentionally kept: the `DASH = "—"`
blank-field UI placeholder in CharacterDetailUi and the preview sample that
mirrors it -- those are deliberate UX, not prose.
Add a deliberately small MVVM About screen: AboutViewModel exposes a StateFlow plus
plain public methods (onToggleMvvmNote) with NO Action sealed type and NO Event channel
— the explicit contrast to the app's MVI screens. AboutScreen collects state and calls
the VM method directly; links open via LocalUriHandler. Static showcase copy lives in
the VM as state to demonstrate the StateFlow-as-content shape. aboutGraph + @Serializable
AboutRoute + aboutPresentationModule wire it in. A code comment and the README explain
why this is MVVM and when each pattern fits.
