fix(ui): thème, textes et lisibilité restants de la revue

Les boutons suivent la couleur d’apparence, les libellés trop petits ou trop techniques sont clarifiés, et le catalogue des fournisseurs se met à jour tout seul.

+
+## Platform
+
+web
+
+## Users
+
+Personnes qui capturent des idées, notes et savoirs au fil du temps et ont besoin de les retrouver, les relier et les actionner — pas seulement de les stocker.
+
+Audiences confirmées (sans hiérarchie exclusive) :
+- étudiants et chercheurs (cours, papers, synthèses, révision) ;
+- freelances et professionnels indépendants (projets, briefs, clients) ;
+- équipes (partage de contexte, agents, Second Brain collectif selon le palier) ;
+- personnes « lambda » qui veulent un second cerveau accessible, pas un outil expert-only.
+
+Situation type : trop de notes / dossiers, recherche trop littérale, idées perdues ; le job est de transformer la capture quotidienne en système vivant (liens, briefing, révision, actions).
+
+## Product Purpose
+
+**Memento** est une application de prise de notes intelligente positionnée comme **Second Brain** : elle relie les idées dans le temps, fait émerger des connexions cachées, et transforme les carnets en système searchable, briefable et actionnable (matin / routines).
+
+Succès produit : l’utilisateur écrit dans Memento et le système lui rend de la valeur *pendant* et *après* l’écriture (Memory Echo, insights, dashboard, flashcards, agents) — pas une pile morte de fichiers.
+
+## Positioning
+
+Pas « une app de notes de plus ». Mécanisme différenciant : un Second Brain qui **se connecte pendant que vous écrivez** — similarité sémantique réelle, ponts entre notes/carnets, aperçu côte à côte, dashboard Second Brain (briefing, pistes, checklist), agents qui **écrivent dans les carnets**, recherche sémantique, révision espacée — plutôt qu’un chat jetable ou un classement manuel de dossiers.
+
+Un concurrent « Keep/Notion générique » ne peut pas honnêtement reprendre la promesse *Second Brain vivant qui se connecte tout seul* sans ces mécanismes.
+
+## Operating Context
+
+- App web principale : `memento-note/` (Next.js App Router), URL prod `https://memento-note.com`.
+- Capture & édition : notes riche / Markdown, carnets, tags, structured views (table/kanban), peek split note liée, publication web, pages interactives.
+- Second Brain au quotidien : dashboard `/home`, Memory Echo dans l’éditeur, `/insights` (clusters sémantiques), `/revision` (flashcards SM-2), agents, rappels, scan Gmail (vols/colis/abonnements).
+- Référence UX métier / prototype : `architectural-grid/` (et base `architectural-grid1/`) — à consulter avant implémentation UI significative ; la vérité produit d’interface suit le prototype quand il y a conflit d’interprétation.
+- Extension navigateur (Web Clipper / Side Panel), serveur MCP, intégrations (Calendar/Gmail pattern).
+- Companion mobile Expo (`memento-mobile/`) existe ; **l’autorité design Impeccable pour ce PRODUCT est le web** (PWA / responsive inclus). Le natif partage la vérité produit mais n’impose pas un langage UI `adaptive` tant qu’il n’est pas le surface principal de craft.
+- Auth : priorité Google OAuth ; email/mdp avec email vérifié obligatoire.
+- i18n : 15 langues ; calendrier iranien + chiffres persans + RTL pour le persan (et arabe) — app et extension.
+- Facturation : paliers BASIC/PRO/BUSINESS/ENTERPRISE, quotas IA, essai abonnement **7 jours** ; BASIC sans MCP ; BYOK possible selon config.
+
+## Capabilities and Constraints
+
+**Capacités confirmées (non exhaustif)** : notes/carnets, recherche sémantique, Memory Echo, insights réseau, dashboard Second Brain configurable, agents, flashcards SM-2, structured views, Web Clipper, MCP (hors BASIC), publication simple/IA, pages interactives, multilinguisme.
+
+**Contraintes durables** :
+- Nom produit : **Memento** uniquement (jamais « Momento ») dans libellés, metadata, pages publiques, docs.
+- Libellés UI via i18n (`memento-note/locales/*.json`) — pas de texte en dur ; pas de marques tierces dans les libellés utilisateur.
+- Qualité UX prioritaire ; solutions long terme plutôt que rustines.
+- Pas de perte de données : jamais de reset/drop/truncate DB sans backup vérifié + confirmation explicite (voir `CLAUDE.md` / règles projet).
+- Quotas IA : réservation atomique avant appel ; chaque usage IA décompte.
+- Une user story / feature à la fois, validation utilisateur avant la suivante.
+- Docs de stories souvent périmées — vérifier le code avant de « (re)développer ».
+
+**Ouvert / hors scope Impeccable init** : détails de roadmap feature-par-feature ; choix esthétiques (monde visuel → `new-work` / `document`).
+
+## Brand Commitments
+
+- Marque : **Memento** ; entité visible « Memento Labs » dans certains pied-de-page.
+- Promesse marketing : Second Brain — « Il se souvient de ce que vous avez oublié » / se connecte pendant que vous écrivez.
+- Voix : claire, concrète, orientée bénéfice utilisateur ; français correct en communication produit FR ; éviter le jargon non expliqué dans l’UI.
+- Référence prototype `architectural-grid` pour les flux métier (liste/carte notes, recherche, insights, sidebar, etc.) — engagement produit confirmé, pas une esthétique figée dans ce fichier.
+
+## Evidence on Hand
+
+- Copy landing et produit : `memento-note/locales/*.json` (ex. `landing.*`), `components/landing-page.tsx`.
+- README produit : `README.fr.md` / `README.md`, guide utilisateur `docs/guide-utilisateur/`.
+- Prototypes UI : `architectural-grid/`, `architectural-grid1/`.
+- Extension : `memento-note/extension/`.
+- Assets promo / démos : `promo-video/` (captures authentifiées, VO EN).
+- **Ne pas inventer** : témoignages clients, logos presse, benchmarks chiffrés non présents dans le repo.
+
+## Product Principles
+
+1. **Second Brain d’abord** — chaque surface renforce connexion, rappel et action ; pas le stockage pour le stockage.
+2. **Valeur pendant l’écriture** — Memory Echo, peek, agents et briefing doivent être exploitables dans le flux réel, pas décoratifs.
+3. **Accessible à la personne lambda, assez profond pour le chercheur** — clarté et aide contextuelle avant jargon ; puissance sans exiger d’être power-user dès le jour 1.
+4. **Monde multilingue réel** — RTL, calendriers et embeddings inclus ; pas d’anglais hardcodé quand l’UI est dans une autre langue.
+5. **Preuve avant promesse** — s’appuyer sur features et copy existantes ; ne pas fabriquer de preuves marketing.
+
+## Accessibility & Inclusion
+
+- Multilinguisme et RTL (fa/ar) sont des exigences produit, pas un bonus.
+- Aide contextuelle (« ? ») et libellés lisibles attendus là où l’UX le demande.
+- Standard WCAG formel non fixé dans cet init : à traiter comme **ouvert** ; viser une UI utilisable clavier / contraste correcte par défaut sur le web sans inventer une certification.

+- `demo-scene-view.tsx:479` : warning eslint exhaustive-deps (`edges` dans useMemo).
