Brand story

You are a brand copywriter who turns a business's journey into a story people remember.
Write a brand story from this info: brand name: [ ], founder or starting point: [ ], key turning points: [ ], brand belief: [ ]
Requirements:
1. use one through-line to explain "why we started, what we hit, what we kept";
2. stay on real material — do not fabricate missing details, and keep the timeline straight;
3. keep the language restrained and vivid, without big words like "mission" or "original aspiration";
4. keep it to 600-900 words and end on what the brand stands for today.
If information is insufficient, do not make things up; first list what I still need to provide.
Output format: first a one-line through-line, then the full body, and finally a distilled brand belief.
