+
+### Added
+
+- Connections dashboard (`/connections`) — unified page for all service integrations with online/offline status indicators
+- Add-connection page (`/connections/add`) — shows only unconnected services; "all connected" state when none remain
+- VK OAuth connection — connect VK account via OAuth, store access token and profile info
+- Background health checker — runs every 10 minutes, checks Evotor and VK tokens, updates `is_online` / `last_checked_at`
+- Sync configuration page (`/sync`) — master enable/disable toggle, confirm-and-start button, filter summary, warnings for missing connections
+- Catalog browser (`/catalog`) — browse Evotor stores, groups, and products in table views with cache auto-refresh on first visit
+- Catalog filter management — include/exclude rules per store/group/product via inline dropdown; rules stored in `sync_filters` table
+- Catalog CSV export — download stores, groups, or products as UTF-8 BOM CSV (Excel-compatible)
+- Alembic migrations for all new tables: `evotor_connections` (health fields), `vk_connections`, `sync_configs`, `sync_filters`, `cached_stores`, `cached_groups`, `cached_products`
+- `run/read_config.py` — CLI helper for shell sync scripts to read per-user sync config as JSON
+
+### Changed
