## What it is
Tacet is a personal noise companion for Paris. It visualizes pollution sonore in real time, gives any street a Serenity Score from 0 to 100, and routes users through the calmest path to where they are going.

## Why it exists
Sonor proved the macro case for cities. Tacet asks the matching question for residents: how do I make this useful at the scale of my walk home, my apartment search, my morning commute? Quiet is a public health resource. Tacet puts it in the pocket.

## How it works
1. Pulls live data from Bruitparif and the RUMEUR sensor network, refreshed every 3 minutes.
2. Computes a Serenity Score per location, simple, legible, defensible.
3. Renders a calm map with a quiet-routing layer for pedestrians.
4. Designed in a Picasso-Blue-Era palette anchored on #001b3a, with a Grain Engine that keeps the surface humanistic rather than synthetic.

## Use cases
- Evaluate a neighborhood before signing a lease.
- Pick the calmest route for a daily commute.
- Compare zones and journal personal exposure.

## Roadmap
Native iOS application with guided navigation and natural language queries.

## Convictions
- Wellness data only matters when it is local, current, and a single tap away.
- A Serenity Score is more useful than a decibel reading, because it is a decision, not a measurement.
- The interface itself should feel quiet.
