## What it is
Cloudflare's public-facing SSL/TLS cipher configuration for its NGINX web servers, tracked as a single configuration fragment. It also includes an OpenSSL patch enabling ChaCha20/Poly1305 with client-preference-aware cipher selection.

## Use cases
- configure modern TLS cipher suites for nginx
- enable ChaCha20/Poly1305 on OpenSSL
- reference production SSL settings from a large CDN
- harden TLS configuration for public web servers
- implement client-preference cipher selection

## When to choose
- you run NGINX and want battle-tested TLS cipher settings
- you need ChaCha20/Poly1305 support with smart cipher prioritization
- you want to mirror Cloudflare's production SSL posture

## When to avoid
- you need a complete turnkey SSL setup rather than a config fragment
- you don't use NGINX or OpenSSL
- you expect supported software rather than a reference configuration
