(For example, a function in a library to compute square roots has
    a purpose that is entirely well-defined independent of the
    application.  Therefore, Subsection 2d requires that any
    application-supplied function or table used by this function must
    be optional: if the application does not supply it, the square
    root function must still compute square roots.)

These requirements apply to the modified work as a whole.  If

## Important Notes

### No Database Changes Required

- Language configuration is entirely file-based
- No database or OpenSearch index updates needed
- Settings are loaded at application startup and cached

### Fallback Mechanism

If a translation is missing in `fess_label_[locale].properties`, Fess automatically falls back to the base `fess_label.properties` (English).

### Language Code Format
