• Auto-save now POSTs only the settings keys that changed, not the full 46-key snapshot every time
• Full cloud upload still happens on first bootstrap (no_remote_settings), client_ahead, and manual “upload all” in Cloud Sync
• sync-init now sends local.settings so the server can compare against your full local state
• Download handling is centralized in applySyncInitResult() (startup, background sync, Cloud Sync modal)
• Sparse server patches (settings_format: "patch") merge locally instead of replacing everything; empty patches only update revision metadata
• POST/sync-init responses strip ok, server, and patch before saving; Rust ignores those envelope keys too
• Expired SEQTA sessions redirect to login instead of leaving you on content with a “session expired” menu
• Weather widget in the header next to the poll; fixed loading/reactivity; compact mode (icon + temp) on narrow widths
• Fallback city/country always editable when weather is on; defaults to Adelaide/AU when blank
• Uses BetterSEQTA+ profile picture sync: cloud upload/download, hash cache, and CloudPfpAvatar in settings
• Cloud settings reference docs and safe missing-key materialization on load (existing branch work)
