-### 3. Split Complex Rules Into Smaller Matchers
-
-Instead of building one all-inclusive pattern, break logic into separate matchers.
-
-**Instead of:**
-
-```regex
-^order-[A-Z]{2}-[0-9]+-(pending|done|failed)$
-```
-
-**Split into:**
-
-```regex
-order-[A-Z]{2}-[0-9]+
-(pending|done|failed)
-```
-
-Apply them sequentially in code if needed. This keeps FSMs smaller and easier to compile.

 ## Byte Search Optimization (Optional)
 
 Patterns that start with an **uncommon character** can be accelerated using an initial byte scan before running the FSM.
