La nouvelle page permet de créer ou modifier un snapshot daté de votre patrimoine : choisissez une date (par défaut aujourd'hui), saisissez la valeur de chaque compte actif groupé par catégorie, puis enregistrez. Le mode est piloté par le paramètre `?date=` de l'URL — si un snapshot existe déjà à cette date, la page bascule automatiquement en mode édition (la contrainte UNIQUE sur `balance_snapshots.snapshot_date` garantit un snapshot par jour). La date d'un snapshot existant est immuable : pour la changer, supprimez puis recréez. Un bouton *Pré-remplir depuis le précédent* copie les valeurs du snapshot antérieur le plus récent (comptes simples uniquement — les comptes cotés seront pris en charge quand l'éditeur coté arrivera). Un bouton *Supprimer* affiche une modal de double confirmation qui exige de retaper la date du snapshot avant d'activer l'action destructive. Seules les valeurs de type simple sont acceptées à ce stade (`quantity` et `unit_price` sont laissés `NULL`) ; l'éditeur coté (quantité × prix unitaire + récupération de prix) arrivera dans une prochaine version. Nouveau hook `useSnapshotEditor` (`useReducer` couvrant tout le cycle de vie) et deux nouveaux composants `SnapshotEditor` + `SnapshotLineRow`. i18n FR/EN sous `balance.snapshot.*` (#146) - **Bilan — fondations du schéma et page Comptes** (route `/balance/accounts`) : première tranche de la nouvelle feature *Bilan*. La migration SQL v9 introduit 5 tables (`balance_categories`, `balance_accounts`, `balance_snapshots`, `balance_snapshot_lines`, `balance_account_transfers`) avec 7 index et seede 7 catégories standard — Encaisse, CELI, REER, Fonds commun, Autre (type simple) + Action et Cryptomonnaie (type coté). La colonne `currency` est verrouillée à `CAD` via une contrainte CHECK au MVP — le support multi-devises arrivera plus tard. La nouvelle page expose deux onglets : *Comptes* (CRUD complet sur les comptes de l'utilisateur, archivage soft plutôt que suppression dure pour préserver les snapshots historiques) et *Catégories* (renommer une catégorie, créer des catégories de type simple, supprimer celles créées par l'utilisateur — les catégories standard sont protégées). Couverture i18n FR/EN complète sous `balance.*`. Snapshots, transferts, rendements et price-fetching premium arriveront dans les prochaines issues ; pour l'instant la route est accessible directement par URL (pas encore d'entrée sidebar) (#138) +- **Récupération de prix premium pour actions (best-effort) et crypto (exchanges directs)** — vie privée préservée via proxy maximus-api.

Aucune licence n'avait été émise en production avec l'ancienne clé, donc ce changement est invisible pour les utilisateurs existants — mais `/licenses/activate` répond désormais, donc l'activation par machine (issue #53) sera débloquée dès la sortie de cette version.

The new page lets you create or edit a dated snapshot of your balance: pick a date (defaulting to today), enter the value of each active account grouped by category, and save. The mode is driven by the `?date=` query parameter — when a snapshot already exists at that date the page automatically flips into edit mode (the underlying `balance_snapshots.snapshot_date` UNIQUE constraint guarantees one snapshot per day). The date of an existing snapshot is immutable: to change it, delete the snapshot and create a new one. A *Prefill from previous snapshot* button copies values from the most recent earlier snapshot (simple-kind accounts only — priced accounts will be handled when the priced editor lands in a later release). A *Delete* button surfaces a double-confirmation modal that requires retyping the snapshot date before the destructive action is enabled. Only simple-kind values are accepted at this stage (`quantity` and `unit_price` are kept `NULL`); the priced editor (quantity × unit price + price fetch) ships in a later release. New `useSnapshotEditor` hook (scoped `useReducer` covering the full lifecycle) and two new components `SnapshotEditor` + `SnapshotLineRow`. FR/EN i18n under `balance.snapshot.*` (#146) - **Balance sheet — schema foundation and accounts page** (route `/balance/accounts`): first slice of the upcoming *Bilan* feature. New SQL migration v9 introduces 5 tables (`balance_categories`, `balance_accounts`, `balance_snapshots`, `balance_snapshot_lines`, `balance_account_transfers`) with 7 indexes and seeds 7 standard categories — Cash, TFSA, RRSP, Mutual Fund, Other (simple kind) plus Stock and Crypto (priced kind). The `currency` column is hardcoded to `CAD` via a CHECK constraint at the MVP — multi-currency support will come in a later release. The new accounts page exposes two tabs: *Accounts* (full CRUD over the user's holdings, soft-archive instead of hard delete to preserve historic snapshots) and *Categories* (rename any category, create simple-kind ones, delete user-created ones — seeded categories are protected). The full FR/EN i18n coverage uses keys under `balance.*`. Snapshots, transfers, returns and the price-fetching premium remain to ship in upcoming issues; for now the route is reachable directly via URL (no sidebar entry yet) (#138) +- **Price-fetching premium for stocks (best-effort) and crypto (direct exchanges)** — privacy preserved via maximus-api proxy. Privacy toggle in Settings to revoke consent. (#160) + ### Changed - **License Ed25519 public key** rotated to match the freshly deployed `maximus-api` license server (now live at `https://api.lacompagniemaximus.com`). No production licenses had been issued against the previous key, so this change is invisible to existing users — but `/licenses/activate` now answers, so machine activation (Issue #53) is unblocked once this release ships.
