+### Native form fields
+
+`src/ui/formField.js` constructs native numeric inputs without listeners or
+application state. Static selects and number inputs use the same `gev-field`
+surface, with explicit compact and inline densities. Feature owners retain
+option identity/order, bounds, parsing, draft values, input/change timing and
+teardown. CCTV effective-pose conversion and tuner/device operations remain
+feature responsibilities. A Vue replacement can reuse this contract and CSS;
+it replaces DOM construction, rather than adding a second state owner.

+### Shared native dropdowns and numeric fields
+
+- Scene and CCTV selects share the default `gev-field` surface. HUD layout and
+  draw colour retain compact density. Radio filter, tuner gain and FM frequency
+  use the same base while retaining their feature-specific skins and layout.
+- The CCTV inline number editor uses `createNumberInput` with its existing
+  precision and inline density. Enter/blur commit, Escape cancellation, frozen
+  camera base, camera-switch guards and disposal remain with CCTV controls.
+- Options, values, native keyboard/typeahead, disabled attributes and browser
+  validity remain native. Frequency bounds, tuner commit timing and calibration
+  parsing are unchanged. Specialized tuner graphics and calibration chips
+  retain their own controls. Provider settings and scene-authoring dialogs are
+  outside this change.
+- `scripts/qa-form-fields.mjs` exercises native selections, number validity,
+  calibration commit/cancel and stale-camera/disposal guards against an installed
+  controller with fixture ports, plus default/Cyber and narrow translated layouts.
