+The shared stylesheet owns field surfaces and disabled opacity; feature and theme
+palettes use `--gev-field-background`, `--gev-field-border-color`,
+`--gev-field-color` and `--gev-field-disabled-opacity`. Radio retains its own
+compact density and arrow space. CCTV owns calibration editor width in

+Cyber supplies a shared-field palette explicitly and keeps its legacy native
+field rules separate, so Radio's palette remains an intentional exception.

+## Shared control CSS ownership
+
+Shared styles own ordinary control surfaces and interaction states; feature CSS
+owns surrounding layout and context-specific sizing. CCTV's calibration editor
+width lives in `ui/styles/cctv.css`, while the shared inline field variant owns
+only density and spinner treatment. Radio supplies its field palette and disabled
+opacity through the `--gev-field-*` variables, retaining compact typography and
+arrow space locally. Cyber supplies shared-field palette variables explicitly;
+its legacy native-field palette rules exclude `.gev-field`. These ownership
+boundaries preserve the current Tactical/Cyber appearance and native behavior.
