Como usar

// Strongly typed options registration with section path from each model.
services.AddOptions<ApplicationOptions>()
    .BindConfiguration(ApplicationOptions.ConfigSectionPath)
    .ValidateOnStart();

services.AddOptions<JwtOptions>()
    .BindConfiguration(JwtOptions.ConfigSectionPath)
    .ValidateOnStart();

O que não fazer

• Do not mutate options classes at runtime to carry request-specific state.
• Do not keep production defaults permissive (for example wildcard CORS fallback).

Extensão pelo produto

• Products can add product-specific option classes implementing IAppOptions.
• Products should keep section names stable to avoid deployment regressions.
