Haven Estates

# Haven — Real-Estate Discovery Platform

## Goal
Build a production-ready real-estate discovery platform called "Haven". Overall vibe: warm architectural calm — linen, oak, daylight; trust through craft, not badges. It should look hand-crafted by a senior product designer — not like a generic template.

## Design System
- **Palette**: warm white #FAF8F5, charcoal #2A2724 text, clay #C4704F accent used only for price tags and primary CTA
- **Typography**: elegant geometric humanist sans — display 56-72px normal weight, prices in medium with tabular nums
- **Grid & spacing**: 12-col grid, 8px b
