Feature cards
One page per MVP feature, written before its code (decision A13). A card is done when a builder — a person or an AI — can work from it without guessing.

## Who and the job
Who uses it, and the one job it does for them.
## Value
Why it exists. What breaks or gets worse without it.
## Placement
Where it sits on mobile, tablet and web — and why there.
## Wireframe
Low-fi, text only. Mobile first, then web. Placement and flow, not colours or fonts.
## States
Empty · loading · error · long content · missing data (e.g. no photo).
## Rules and edge cases
The domain rules this feature must respect, with the reason for each.
