## Summary Implements server-side remote configuration to decouple runtime behavior from build artifacts, enabling dynamic configuration updates without redeployment. ## Technical Changes - **Replaced** build-time constants (`__MIXPANEL_TOKEN__`, `__BUILD_FLAGS__`) with runtime configuration loaded from `/api/features` - Configuration now sourced from `window.__CONFIG__` (hydrated from `/api/features` endpoint) - **Added** `src/platform/remoteConfig/` service that polls server configuration every 30 seconds - **Modified** application bootstrap sequence in `main.ts` to load remote config before module initialization (required for cloud builds) - **Removed** global constants: `__BUILD_FLAGS__`, `__MIXPANEL_TOKEN__`. Runtime subscription enforcement toggle via `subscription_required` flag - Server health alerts with variant-based severity rendering (info/warning/error) via topbar badges ## Rationale - **Build-once-deploy-anywhere**: Single immutable artifact promoted through environments (staging → production) - **Zero-downtime configuration**: Update behavior without rebuilding or redeploying the application - **Incident response**: Disable features or display alerts dynamically in response to outages or degraded service - **Instant rollback**: Revert configuration changes server-side without artifact redeployment - **Progressive delivery**: Enable A/B testing, canary releases, and user/region-based configuration - **Environment parity**: Eliminate configuration drift between staging and production builds - Decouples deployment cadence from configuration changes - Enables GitOps workflows for configuration management separate from code deployments - Supports real-time operational control of client behavior - Reduces build matrix complexity (no per-environment builds) ┆Issue is synchronized with this [Notion page](https://www.notion.so/PR-6246-change-cloud-feature-flags-to-be-loaded-dynamically-at-runtime-rather-than-set-in-build-2966d73d3650811cbb41c9093961037a) by [Unito](https://www.unito.io)
