 * Two passes, and the split is the mechanism behind FR-3's "the alternatives
 * line drops before the decision itself drops". Dropping from the bottom alone
 * would not deliver it: with `[d1, alt1, d2, alt2]` a cut landing on `d2` drops
 * that decision *and* its continuation together, and `alt1` has already spent
 * budget `d2` needed. Charging continuations only after every affordable `line`
 * is kept makes the guarantee hold at every budget instead of most of them.
 *
 * When no entry carries a continuation, pass two is a no-op and the output is
 * byte-for-byte what pass one alone produced — which is how "decisions without
 * alternatives render exactly as they do today" is satisfied structurally.
