+/**
+ * Flag reads of a `useFormField` / `useFieldGroup` ref that don't fall back to
+ * the `useComponentProps` proxy.
+ *
+ * `size`, `color`, `highlight` and `disabled` come back holding only what the
+ * wrapping `<UForm>` / `<UFormField>` / `<UFieldGroup>` supplied, so a bare
+ * `size.value` silently drops `<UTheme :props>` and `app.config` defaults. The
+ * fix is always the same shape, either inline or hoisted into a computed:
+ *
+ * ```ts
+ * size: formFieldSize.value ?? props.size
+ * const disabled = computed(() => formFieldDisabled.value ?? props.disabled)
+ * ```
+ *
+ * So the rule allows a read only when it sits in a `??` chain that ends in a
+ * `props.<key>` member access, and reports it everywhere else. Chaining two
+ * refs (`fieldGroupSize.value ?? formFieldSize.value ?? props.size`) is fine.
+ *
+ * Templates are checked too, and more strictly: refs auto-unwrap there, so an
+ * unresolved `:size="formFieldSize"` has no `.value` to key off and reads
+ * exactly like the resolved `:size="size"`. Since the resolution always belongs
+ * in setup anyway, any appearance of one of these refs in a template is
+ * reported outright.
+ *
+ * Not auto-fixable: the right landing spot is often a shared computed rather
+ * than the use site, and appending `?? props.x` to the wrong branch of a
+ * ternary would change behaviour silently.
