v2.2.1

Added

• Portainer install guide, for both a pasted stack and a Git/GitOps stack. Portainer never places a .env next to the compose file, so a stack manifest has to list every variable explicitly - docs/docker-compose.portainer.yml does, and a Git stack should point its compose path at it.

Fixed

• Yuvomi kept a browser's GPU busy while nothing was happening. The tinted shapes drifting behind the interface carried their blur on the same element that moved, so the browser re-rendered that blur on every single frame - for as long as the page stayed open. Measured on an idle dashboard, the app now holds 60 frames per second where it managed about 20, and a laptop no longer heats up with Yuvomi merely open in a tab.
• A red "unexpected error" appeared when the app started. Behind it was a browser notice about layout measurements being delivered one frame later - routine, not a fault, and nothing was ever broken by it.
• Deploying from a Git-managed stack (Portainer, Komodo, Dockge) no longer fails with env file .env not found. The repository's docker-compose.yml is written for a local clone with a generated .env beside it; a missing one is now tolerated instead of aborting the deployment.
