3 * make-cinematic.cjs — compile cinematic.json → plan.json (then make-composition.cjs).
4 * CINEMATIC MODE, raised to BLOCK level. The agent authors thought-BLOCKS — lines of
5 * words, which plane each block stacks in, at most one promoted HERO word — and the
6 * compiler lowers that into the classic plan.json with everything deterministic
7 * generated, so the Cinematic failure modes seen in the wild become impossible:
8 *   - READING ORDER by construction: lines stack in declaration order inside a flex
9 *     plane (spoken order = visual order; a hero can never sit below later words)
10 *   - timings from the transcript BY SEQUENCE (no hand-copied times; duplicates by position)
11 *   - accumulate-within-block / page-flip-between-blocks rhythm generated:
12 *     lines of a block share the block's out (they accumulate, then clear together
13 *     when the next block's first word lands); the NEXT block enters fresh
