Alphabetic String RAG Generator

I need a Random Access Generator built that focuses solely on strings rather than numbers or custom objects. The generator must output alphabetic strings—no digits, no hex characters. At runtime I want to be able to: • Specify the desired string length (single character up to a user-defined maximum). • Decide whether the output should be uppercase-only, lowercase-only, or a mix (I did not lock this choice in yet, so please leave it configurable). • Request single strings or batches and receive them instantly without noticeable lag. Implementation details I care about: • A clean, well-documented core function or class in Python, JavaScript, or another mainstream language you propose. • A simple test script or UI snippet that shows the generator producing sample output for the three case-style options. • Clear instructions so I can drop the code into an existing project and call the generator in one line. Deliverables 1. Source code with inline comments. 2. README explaining setup, usage, and any dependencies. 3. Brief note on how randomness is achieved (e.g., crypto-secure vs. pseudo RNG). If any part of the spec is unclear, feel free to suggest refinements—speed and clarity are my priorities.
