v2 : les 14 écrans — le tour complet de la démocratie d'exercice

- Aujourd'hui (Fil 13 sections + capture sticky) + Le chemin (tunnel 2 gestes,
  Q0 inline, 3 chips, dérogation asymétrique, alternatives réglage/consignation)
- Registre + fiche décision (timeline, périmètre premier/second lieu auditable,
  affluence non-ignorable, S'instruire condensé, éléments + cartographie de
  clôture, épreuve du réel, Remettre en question, PV A4, gravure)
- Salle de vote 5 modalités (consentement, nuancé+histogramme, binaire hérité
  avec jauge inertielle, Réglage collectif complet — faisceau, médiane basse,
  Pour moi, Explorer, cristallisation-geste —, élection à départage humain)
- Textes (Pacte en clair, document vivant, diff, vue projetée, Atelier des
  formules porté du v1 sur le moteur unique) + Mandats (faits comptés, feux
  de la rampe, wizard 3 étapes) + Observatoire (consigner→observer→protocoliser)
- Onboarding 7 gabarits + Données locales (export/import, attributs, atelier)
- voting→framing gardé (Reformuler d'un réglage figé non cristallisé)
- Pages v1 supprimées (login, documents, mandates, protocols, sanctuary,
  tools, decisions/new) — 342 tests verts, build zéro erreur
