Detailed Description

Minimal safe string formatting for embedded systems.

Provides basic printf-style formatting optimized for embedded use:

• d, i: signed integer
• u: unsigned integer
• x, X: hex (lower/upper)
• s: string
• c: character
• f: float (fixed precision, no scientific notation)
• %%: literal percent

No dynamic allocation. Fixed buffer output.
