Let me analyze the source material and write a polished summary following all the guidelines.

Key facts from the source:

- Dbrand created a Companion Cube case mod for Steam Machine

- Over 100,000 pre-orders

- Dbrand never asked Valve for permission/license to use Portal IP

- Valve's legal team demanded takedown after product went on sale

- Dbrand tried to negotiate, Valve declined

- Dbrand admits Valve was right

- Refunds being issued including international shipping fees

- Product cancelled

Now I need to write 180-250 words across 3-4 paragraphs (45-65 words each), with selective bolding (3-5 terms total), and end with a concrete statement.

Let me draft:

Paragraph 1 (core news): Dbrand's Companion Cube case for Valve's Steam Machine attracted over 100,000 pre-orders before the company admitted it never secured a license from Valve to use Portal intellectual property. The accessory transformed the gaming PC into the iconic weighted companion cube from the puzzle series, but Valve's legal team moved quickly after launch to demand its removal.

Paragraph 2 (context): In a candid Reddit post, Dbrand acknowledged the oversight and confirmed Valve declined to negotiate a retroactive agreement. The skin maker accepted responsibility, stating Valve alone controls how its franchise assets are used. Refunds for all pre-orders, including international shipping fees, began processing this week.

Paragraph 3 (closing): The episode underscores how even established accessory makers can misjudge IP boundaries when capitalizing on beloved gaming iconography. Dbrand's Companion Cube joins the cake as another Portal promise that never materialized.

Now let me count words:

Para 1: ~45 words

Para 2: ~45 words

Para 3: ~35 words

Total: ~125 words - too short. Need 180-250.

Let me expand:
