UI: diversify peer colors; smarter geo notifications; 21m live location

- Use minimal-distance hue palette for mesh and geohash lists; align chat sender colors with list palette.
- Add foreground geo notifications for different channels; deep-link to bitchat://geohash/<gh>; per-geohash 60s cooldown; respect self/blocks.
- Global geohash sampling runs outside the sheet; delegate handles deeplinks and suppresses when already in-channel.
- Switch location channel sheet to continuous CoreLocation with 21m distance filter; add config knob.
- Only link geohash hashtags when standalone (no @name#abcd or word#abcd).
- Include mesh-reachable peers in mesh counts and in "bitchatters nearby" notification.
- Add TransportConfig knobs for palette and geo notifications.

 > Private messages have not received external security review and may contain vulnerabilities. Do not use for sensitive use cases, and do not rely on its security until it has been reviewed. Now uses the [Noise Protocol](http://www.noiseprotocol.org) for identity and encryption. Public local chat (the main feature) has no security concerns.

 ## Features
 
-- **Dual Transport Architecture**: Bluetooth mesh for offline + Nostr protocol for internet-based messaging
-- **Location-Based Channels**: Geographic chat rooms using geohash coordinates over global Nostr relays
-- **Intelligent Message Routing**: Automatically chooses best transport (Bluetooth → Nostr fallback)
 - **Decentralized Mesh Network**: Automatic peer discovery and multi-hop message relay over Bluetooth LE
 - **Privacy First**: No accounts, no phone numbers, no persistent identifiers
-- **Private Message End-to-End Encryption**: [Noise Protocol](http://noiseprotocol.org) for mesh, NIP-17 for Nostr
+- **Private Message End-to-End Encryption**: [Noise Protocol](http://noiseprotocol.org)
 - **IRC-Style Commands**: Familiar `/slap`, `/msg`, `/who` style interface
 - **Universal App**: Native support for iOS and macOS
 - **Emergency Wipe**: Triple-tap to instantly clear all data
 - **Performance Optimizations**: LZ4 message compression, adaptive battery modes, and optimized networking
 
+
 ## [Technical Architecture](https://deepwiki.com/permissionlesstech/bitchat)
 
-BitChat uses a **hybrid messaging architecture** with two complementary transport layers:
+### Binary Protocol
+bitchat uses an efficient binary protocol optimized for Bluetooth LE:
+- Compact packet format with 1-byte type field
+- TTL-based message routing (max 7 hops)
+- Automatic fragmentation for large messages
+- Message deduplication via unique IDs
 
-### Bluetooth Mesh Network (Offline)
+### Mesh Networking
-
+- Each device acts as both client and peripheral
-- **Local Communication**: Direct peer-to-peer within Bluetooth range
+- Automatic peer discovery and connection management
-- **Multi-hop Relay**: Messages route through nearby devices (max 7 hops)
+- Adaptive duty cycling for battery optimization
-- **No Internet Required**: Works completely offline in disaster scenarios
-- **Noise Protocol Encryption**: End-to-end encryption with forward secrecy
-- **Binary Protocol**: Compact packet format optimized for Bluetooth LE constraints
-- **Automatic Discovery**: Peer discovery and connection management
-- **Adaptive Power**: Battery-optimized duty cycling
-
-### Nostr Protocol (Internet)
-
-- **Global Reach**: Connect with users worldwide via internet relays
-- **Location Channels**: Geographic chat rooms using geohash coordinates
-- **290+ Relay Network**: Distributed across the globe for reliability
-- **NIP-17 Encryption**: Gift-wrapped private messages for internet privacy
-- **Ephemeral Keys**: Fresh cryptographic identity per geohash area
-
-### Channel Types
-
-#### `mesh #bluetooth`
-
-- **Transport**: Bluetooth Low Energy mesh network
-- **Scope**: Local devices within multi-hop range
-- **Internet**: Not required
-- **Use Case**: Offline communication, protests, disasters, remote areas
-
-#### Location Channels (`block #dr5rsj7`, `neighborhood #dr5rs`, `country #dr`)
-
-- **Transport**: Nostr protocol over internet
-- **Scope**: Geographic areas defined by geohash precision
-  - `block` (7 chars): City block level
-  - `neighborhood` (6 chars): District/neighborhood
-  - `city` (5 chars): City level
-  - `province` (4 chars): State/province
-  - `region` (2 chars): Country/large region
-- **Internet**: Required (connects to Nostr relays)
-- **Use Case**: Location-based community chat, local events, regional discussions
-
-### Direct Message Routing
-
-Private messages use **intelligent transport selection**:
-
-1. **Bluetooth First** (preferred when available)
-
-   - Direct connection with established Noise session
-   - Fastest and most private option
-
-2. **Nostr Fallback** (when Bluetooth unavailable)
-
-   - Uses recipient's Nostr public key
-   - NIP-17 gift-wrapping for privacy
-   - Routes through global relay network
-
-3. **Smart Queuing** (when neither available)
-   - Messages queued until transport becomes available
-   - Automatic delivery when connection established
