Show HN: Lightweight C++23 S3 client with no extra deps (just curl and OpenSSL)

This submission presents a C++23 S3 client emphasizing minimal dependencies, specifically `libcurl` and `OpenSSL`. This addresses a critical developer pain point in C++ ecosystems: dependency bloat and the associated complexities in build processes, security audits, and binary size. For performance-sensitive applications or environments with strict dependency policies, a client with such a lean footprint offers significant operational advantages. While positioned as a learning project and a 'toy' client, the underlying architectural choice of minimal external libraries holds substantial commercial appeal. Enterprises often seek to reduce attack surface and simplify deployment, making solutions that avoid extensive third-party library chains highly desirable. The project's current state, acknowledging potential bugs against AWS and the author's C++ learning curve, indicates it is not production-ready. However, it validates the market demand for highly optimized, dependency-light infrastructure components within the cloud storage domain.
