 * Accepts both 33-byte compressed (SEC 1 §2.3.3, 0x02 / 0x03 || x) and
 * 65-byte uncompressed (SEC 1 §2.3.4, 0x04 || x || y) inputs. The WASM
 * ABI consumes only the 33-byte compressed form; the wrapper layer
 * normalises 65-byte inputs to compressed before staging into WASM
 * memory (see `normalizePublicKey` in `./index.ts`). Constant-time is
 * not required at pk import since pk is public material.
 *
 * Length-only at this layer; on-curve / canonical-x checks happen in
 * `pointDecompress` (verify) or via the fault-injection pk-mismatch
 * trap (sign).
