+/* Zupt — AES-256-CTR 4-Block Pipeline via AES-NI (Jasmin)
+ * Copyright (c) 2026 Cristian Cezar Moisés — MIT License
+ *
+ * CT-REQUIRED: AES-NI has no data-dependent timing.
+ *
+ * Interleaves 4 independent counter blocks through the AES round
+ * pipeline. AES-NI has 4-cycle latency, 1-cycle throughput — so
+ * 4 independent blocks saturate the pipeline for ~4× throughput.
+ *
+ * Expected: ~3.5 GB/s AES-256-CTR on modern x86-64 (Zen3/Alder Lake).
+ *
+ * Interface:
+ *   zupt_aes256_ctr4(out, in, key, ctr, nblocks)
+ *   Encrypts nblocks×16 bytes. Counter is incremented in the last 8 bytes
+ *   (big-endian) after each block. Processes 4 blocks per iteration;
+ *   remaining 1-3 blocks fall back to zupt_aes256_blk.
+ *
+ * NOTE: This is the Jasmin source for documentation. The actual linked
+ * assembly is in zupt_aes_ctr4.s (hand-written to match this logic).
+ */
+
+/* See zupt_aes_ctr4.s for the production assembly.
+ * This .jazz file documents the algorithm but is not compiled
+ * (jasminc is not required at build time). */
