Subject: [PATCH] =?UTF-8?q?Fix=20orders=20defpage:=20length=E2=86=92len=20?=
 =?UTF-8?q?primitive,=20handle=20=5FRawHTML=20in=20serialize()?=
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Fix undefined symbol 'length' → use 'len' primitive in orders.sx
- Add _RawHTML handling in serialize() — wraps as (raw! "...") for SX wire format
  instead of falling through to repr() which produced unparseable symbol names
