`SettingsRoot` and the `sidebar.settings` occupancy moved to ui-settings-general,
but both READMEs still read as if ui-settings were the shell. ui-settings now
documents what it actually is — the `ctx.settingsScope` transport plus the slot
type declarations, with the bind ownership, refresh triggers, write revision
handling, and decode refusal a preference row must know — and records the
loopback-only and single-field write gaps in place of two limitations that no
longer exist. ui-settings-general documents the shell it now renders. The stale
module JSDoc on both halves follows.
