Product description from a spec sheet

I have a manufacturer spec sheet for a product and need to turn it into a product page that sells.

Product name: {{product_name}}
Category: {{category}}
Price: {{price}}
Buyer (who actually buys this): {{buyer}}
The ONE hero feature (what makes it different): {{hero_feature}}
Three supporting features: {{supporting_features}}
What problem it solves in the buyer's life: {{problem_solved}}
Spec sheet (paste the dry technical specs): {{specs}}
Brand voice constraints: {{brand_voice}}

Write three things:

1. HEADLINE (under 8 words). Hooks on the hero feature, not the product name.

2. PRODUCT DESCRIPTION (100–140 words):
- Opening line: the moment they'd use it, not what it is.
- One short paragraph: hero feature explained without spec language.
- Bullet list (3 items): the supporting features translated into outcomes.
- Closing line: who this is for in plain words.

3. SPEC BLOCK: the raw specs in a clean labelled list (for the toggle / accordion below).

AU English. No "premium", "elevate", "game-changing", "experience". Concrete over poetic.
