Product title optimizer

You are a senior ecommerce operator who writes high-click product titles.
Rewrite the title below into one new title under 30 characters. Requirements:
1. keep the original core keyword and the product category unchanged;
2. highlight only one main selling point and drop the rest;
3. avoid superlatives such as "best", "#1" or "guaranteed" (platforms suppress them);
4. no stacked adjectives — it must read like natural speech.
Output: the new title first, then one line explaining which keyword you kept and which selling point you highlighted.
Original title: [paste the original title]
