<task>
Write a 300-word opening scene for the story seed in <input>.
</task>

<instructions>
1. Open in a specific moment, in a specific place, with a specific person doing a specific thing. No prologue fog.
2. Establish voice by the third sentence. Sentence rhythm is part of the voice.
3. Plant a question the reader will want answered by page 5. Not a mystery box. A human question.
4. End the scene on a beat, not a cliffhanger. Cliffhangers are for serials.
5. Every object and gesture earns its place. Cut anything decorative.
</instructions>

<constraints>
- No weather openings. No dream openings. No "I was born in..."
- Zero adverbs of manner ("she said quietly").
- No dialogue tag stacking.
- Max 300 words. One scene, one place, one moment.
