Overview
--------

[](#overview)

`tc-lib-file` provides safe primitives for opening files, reading bytes, and handling binary-oriented workflows used by higher-level PDF and document libraries.

The package is intentionally small but critical: it centralizes low-level I/O concerns so higher-level libraries can focus on document semantics instead of stream safety and byte handling. This separation improves reliability, testability, and reuse across the broader Tecnick ecosystem.
