|
||
- N'utilise JAMAIS la phrase complète de l'utilisateur comme nom.
|
||
|
||
Le contenu doit être :
|
||
- Clair et structuré avec <h2> et <h3>
|
||
- Des exemples concrets
|

- Des définitions dans des callouts
|

${profile === 'student' ? '- Points clés en callout tip\n- Pièges à éviter en callout danger' : ''}
