/* Lagos Life checkbox. Owner 5c. Spec: inputs.html#checkbox-radio.
   Replaces the native 16px box with accent-color in leaf (scr/signup-sheet-bottom-light-390).

             <input class="ll-checkbox__box" type="checkbox" name="terms">
             <span class="ll-checkbox__label">I'm <b>18+</b> and I agree to the …</span>
           </label>
   The whole label is the target (44px or taller). Native input, so Space toggles and forms submit as usual. */
