+ * LabeledField — Compound component that correctly links <Label> to <Input>
+ * (or <Textarea>) via a shared `React.useId()` id.
+ *
+ * This is the canonical fix for the DevTools accessibility warning:
+ *   "No label associated with a form field"
+ *
+ * Usage:
+ *   // Instead of:
+ *   <Label>Email</Label>
+ *   <Input type="email" />
+ *
+ *   // Use:
+ *   <LabeledField label="Email" name="email" type="email" />
+ *
+ *   // With error:
+ *   <LabeledField
+ *     label="Email"
+ *     name="email"
+ *     type="email"
+ *     required
+ *     description="Usado para login"
+ *     error={errors.email?.message}
+ *   />
+ *
+ *   // Textarea variant:
+ *   <LabeledTextarea label="Observações" name="obs" rows={4} />
