GreenCoast — Privacy-First, Shardable Social (Dockerized)

Goal: A BlueSky-like experience with shards, zero-trust, no data collection, E2EE, and easy self-hosting — from x86_64 down to Raspberry Pi Zero.
License: The Unlicense (public-domain equivalent).

This repo contains a minimal, working shard: an append-only object API with zero-data-collection defaults. It’s structured to evolve into full federation, E2EE, and client apps, while keeping Pi Zero as a supported host.
