Validation Methodology

Validate extension and MIME detection before processing.
Benchmark performance with small and larger files.
Test malformed-input handling and error messaging.

Matriz de fixtures

Use the curated STL matrix to choose the right clean, edge-case, and broken fixtures for this format.
