chore(landing): single-source RESET_FADE_MS and drop the unused card frame size

RESET_FADE_MS now lives only in the shared loop-engine hook module; the
enterprise stage-data copy is removed. SolutionsVisualFrame loses its
size prop and cardHeight constant - only the 16:9 hero preset remained
in use after the split-variant removal.
