Poem

A bunny hops through chapters nine,
Leaves trails of patterns, crisp design.
Factory, Builder—names in a row,
Singleton’s burrow, Prototype’s glow.
Abstract fields where ideas convene—
I thump my paws: “Creation, clean!”

9-11: Use a single Persian term for consistency

Prefer one of "سازنده" or "ایجادی" throughout; suggest aligning Line 11 with the title.

Apply:

-به طور کلی، الگوهای طراحی ایجادی در پی آن هستند که **زمان، مکان و چگونگی ایجاد اشیاء** را به صورت انتزاعی مدیریت کنند.

13-14: Fix typos and punctuation

Join “الگو های” → “الگوهای”, place colon tight to the heading, and use ZWNJ in “شده‌اند”.

7-7: LGTM on intro and tooltip usage

The inline tooltip and opening paragraph read well.
