+/**
+ * v2.5.20 — Kanonische JSON-Serialisierung, kompatibel zum Python-Tool
+ * (`canonical_json_bytes`):
+ *  - Keys lexikografisch sortiert.
+ *  - Trennzeichen ohne Whitespace: "," / ":".
+ *  - `ensure_ascii=False` ⇒ Unicode-Strings werden nicht escapet, ausser den
+ *    minimal nötigen JSON-Escapes (`\"`, `\\`, Steuerzeichen < 0x20).
+ *  - `null` für JSON-Null; `JSONObject.NULL` und Kotlin-`null` gleich behandelt.
+ *
+ * Diese kanonische Form ist die Eingabe für die ECDSA-P256-SHA256-Signatur.
