#### Environment

- Angular:
- CDK/Material:
- Browser(s):
- Operating System (e.g. Windows, macOS, Ubuntu):

Inizia con le riproduzioni StackBlitz collegate e confronta le varianti dei campi modulo legacy, standard, fill e outline con un pulsante nella stessa riga. Esamina i selettori .mat-form-field-appearance-* elencati e determina se uno stile di componente condiviso può allinearne le altezze senza regole personalizzate per variante. Il lavoro è completato quando le varianti e il pulsante hanno un’altezza della riga coerente usando un unico stile manutenibile.
