/* Input Field — LittleLives design system
   9 field-type variants × 5 interaction states. Composition:
     .ll-field                       — outer block (label + box + assistive row)
     .ll-field__label                — label row (text + required* / (optional))
     .ll-field__box                  — the input box (min 48px, radius 8, 1.5px border)
     .ll-field__bottom               — flex row: assistive text + counter

   States are driven by:
     - real :hover / :focus-within on .ll-field__box
     - force classes for the storybook matrix:
         .ll-field.is-hover, .ll-field.is-focus, .ll-field.is-readonly, .ll-field.is-error

   The focus ring is rendered as box-shadow so layout does not shift.
