+/**
+ * sync-reels.mjs — single-source-of-truth guard for the flip-book pipeline.
+ *
+ * WHY: the studio serves the public video from `reels/<slug>-flipbook.mp4`, but
+ * `build-page.mjs` only COPIES the render into `reels/` once, at page-build time.
+ * Any RE-RENDER after that writes to `flipbooks/<slug>/renders/<slug>-flipbook.mp4`
+ * and silently leaves `reels/` (the served file) stale — so the live page shows an
+ * old cut while "deploy OK" reports success. (Hit live on Majilite Metallics,
+ * 2026-08-10, TK-10413.)
+ *
+ * FIX: run this as the project's PREDEPLOY_HOOK. Before every deploy it copies each
+ * render into `reels/` whenever the render is newer or differs in size, so the
+ * served file can never lag the freshest render again. It only SYNCS (never gates);
+ * it exits non-zero only on a real IO failure.
