@@ -325,6 +325,7 @@ Use `.server.ts` files for server-side code to isolate API keys.
 - For dashboard forms, prefer `@cio/ui/custom/*-field` wrappers (for example `InputField`, `TextareaField`, `CheckboxField`) so label/error/spacing behavior stays consistent.
 - Use base primitives (`@cio/ui/base/input`, `@cio/ui/base/textarea`, `@cio/ui/base/checkbox`, `@cio/ui/base/label`) only when creating/updating reusable UI components or when no custom field wrapper exists.
 - In app-level form UIs, do not introduce native form controls (`<input>`, `<textarea>`, `<label>`) when equivalent `packages/ui` components exist.
+- **Icon-only buttons** (a `Button` whose content is just an icon, e.g. `size="icon"`) must use `variant="secondary"`.
 - **Theme color classes:** Classes that use colors from `packages/ui/src/index.css` (e.g. `text-muted-foreground`, `text-primary`) must be prefixed with `ui:` in dashboard code so they resolve against the UI theme (e.g. `ui:text-muted-foreground`, `ui:text-primary`). Only color-related utilities need the prefix; layout/sizing classes like `rounded`, `border`, `p-4` stay unprefixed (Tailwind defaults).
