   LENUTA-F-398 — Écrans d'authentification, direction C « Manufacture nocturne »
   (même univers que la page d'accueil F-397 ; maquette Figma « Lenuta —
   Explorations accueil », page « Connexion »).

   Feuille UNIQUE de templates/auth_base.html (app.css n'y est plus chargée).
   Toutes les règles sont portées par body.auth-page / body.auth-page : aucune autre
   page n'est touchée. Polices OFL auto-hébergées (static/fonts, licences
   jointes), aucun CDN, aucune feuille importée.

   Contrastes WCAG 2.1 mesurés (rapport de revue F-398, § Mesures) :
     ivoire  #f4efe6 sur nuit #0f0e0c / surface #191714 → 16.85 / 15.62
     gris    #b8afa0 sur nuit / surface                → 8.89 / 8.24
     laiton  #c2a06a sur nuit / surface                → 7.84 / 7.27
     nuit sur bouton ivoire                            → 16.85
     placeholder #948b7d sur champ nuit                → 5.74
     bordure champ #8a8276 sur champ / surface         → 5.09 / 4.71 (≥ 3:1)
     erreur #e8a598 sur #241815                        → 8.44
   Cibles tactiles ≥ 44 px (liens, boutons, champs).

   Cache : /static est servi `immutable` (main.py) — une police REMPLACÉE doit
   changer de nom de fichier.
