Theming
sE2EEnd supports branding customisation through environment variables and runtime configuration. No rebuild is needed.
Storage
sE2EEnd supports two storage backends for encrypted files: local filesystem and S3-compatible object storage.
Instance Settings
Instance-wide settings are stored in the instance_settings table (simple key/value) and can be changed at runtime from the Admin dashboard (Settings panel) — no restart or redeploy needed. Defaults are seeded by database migrations.
