The standard Android back-gesture preview — the surface scales to ~90%, rounds
its corners and shifts toward the swiped edge as the gesture is dragged, then
commits or springs back. Plus rememberReduceMotion() to honour the system
"remove animations" setting. Drawn from Calendula's CalendarTransitions so both
apps preview back the same way; adds the activity-compose dependency.

FloretExpressiveTheme(lightScheme, darkScheme, darkTheme, dynamicColor,
typography) holds the family's theme mechanics — dynamic-colour resolution
(API 31+), system light/dark fallback, and the STANDARD motion scheme — while
each app supplies its own seed-derived colour schemes, so the look stays
per-app and the machinery is shared. rememberNavSlideSpec() shares the fast
spatial nav slide. android-library, Compose-only.
