+
+<objective>
+Fix dark mode visibility for step headings, DeploymentStep native form controls, and ReviewStep security checkbox.
+
+Purpose: All four wizard step headings are currently invisible in dark mode (browser default black text on dark background). DeploymentStep's native form controls (labels, legends, checkboxes, radios) are also unstyled and invisible. These are regressions from the v1.2 UI overhaul where structural elements were migrated but their text styling was omitted.
+
+Output: All step components render readable text and properly styled controls in both light and dark mode.

+Fix FieldRenderer select element dark mode visibility by adding background and text color semantic tokens.

+Purpose: The `<select>` element in FieldRenderer has no background or text color class, causing browsers to apply a white system background in dark mode — making selected text invisible. Adding semantic token classes ensures the select matches the app's dark theme.
