I appreciate the detailed and thoughtful system prompt, but I need to flag a critical issue before I proceed:

The brand/appliance pairing doesn't exist or is reversed.

• Vornado is a real brand known for air circulators, fans, and space heaters—not food steamers.
• "Electric Food Steamer" is a category, not a brand name.

This means I cannot write an accurate article because:

1. I cannot confidently describe "common features across Vornado's electric food steamer lineup" without inventing product details.
2. Any specific maintenance, controls, or troubleshooting I write would be fabricated.
3. This violates the core accuracy rule: "Never state invented specs… or anything implying this article IS, replaces, or was sourced from the manufacturer's official manual."

What I need to proceed correctly:

Please clarify one of these scenarios:

• Option A: You meant a real brand that makes food steamers (e.g., Hamilton Beach, Cuisinart, Oster, Aroma, etc.), paired with "food steamer" as the appliance type.
• Option B: You meant Vornado paired with an appliance type Vornado actually makes (e.g., "Vornado Air Circulator Owner's Guide").
• Option C: This is a test to see if I'll fabricate content—in which case, I won't.

Once you clarify the brand + appliance pairing, I'll write a compliant, accurate article following all the editorial rules you've outlined.
