app.bluvy.tube.preferences

Bluvy Tube-specific per-app appearance preferences for one account, written to that account's own repo at rkey `self`. Not required or validated by the PDS or any other AT Protocol app — Bluvy Tube reads this back itself at login to server-render the correct theme and remove the theme flash-of-unstyled-content. Each Bluvy app keeps its own independent record in its own namespace; this one is Bluvy Tube's. See App\Service\AppearanceService in the Bluvy Tube source for the writer.
