"""Rendu HTML « Précision sur séquences numériques » — Sprint 86.

Suite directe ``picarones/core/numerical_sequences.py``
(Sprint 85) + câblage runner Sprint 86.

Pattern identique aux autres rendus : server-side, pas de JS,
anti-injection systématique.

Vue
---
Tableau moteur × catégorie (year / roman / foliation / currency
/ regnal) × score strict ; une ligne par moteur, une cellule
colorée par cellule.  Une seconde ligne donne le score ``value``
(en plus petit).  Catégorie omise si **aucun** moteur n'a de
GT exploitable pour elle.

Adaptative : ``""`` si aucun moteur n'a de
``aggregated_numerical_sequences``.
