     #gc-years      querySelector — reads .value
                    setInputError → classList.add/remove('gc-input-error')
     #resultText    style.display = 'none'|'block' (inline override)
                    style.borderLeftColor = '#d63638' (error) | green (success) (inline)
                    writes .innerHTML with <strong>, <br>, <small>
     .gc-calculate-btn  e.target.classList.contains() click trigger
     .gc-input          class on both inputs
                        e.target.classList.contains('gc-input') on Enter key
     .gc-input-error    classList.add/remove on both inputs
     .gc-result         display:none — JS sets style.display='block'
                        border-left must exist so JS inline override works
