"""Tests Sprint 62 — vue HTML « Profil philologique ».

Couvre :

1. Sections individuelles : rendu correct quand au moins un moteur a
   du signal pour le module donné ; chaîne vide si aucun.
2. Agrégateur : 6 sections présentes si les 6 modules ont du signal,
   sinon seulement les sections avec signal.
3. Adaptive masking complet : aucun moteur n'a de signal → ``""``.
4. Anti-injection HTML : noms de moteurs / catégories / caractères
   contenant ``<script>`` correctement échappés.
5. Cellules : code couleur appliqué, valeurs en %.
6. Pas de classification automatique (le mot
   « diplomatique » / « modernisant » apparaît seulement dans la
   note explicative, jamais comme étiquette de moteur).
7. Intégration dans le rapport HTML complet (FR + EN).
8. Complétude i18n : toutes les clés ``philo_*`` présentes en FR et EN.
