The single-clip razor path guards splits with isSplitTimeWithinBounds, which keeps a SPLIT_BOUNDARY_EPSILON_S margin from each clip edge so a cut never produces a degenerate near-zero slice. The split-all path filtered with raw `splitTime > start && splitTime < end` instead, so it accepted cuts inside that margin (and on clips shorter than two epsilons that the single path always rejects), producing the very degenerate slice the epsilon exists to prevent. Extract the shared predicate canSplitElementAt and a selectSplittableElements helper, and route both razor paths through them so the two stay consistent. Adds unit coverage for the new helpers, including the regression where a sub-epsilon clip with an interior split time must not be selected.
