/* fincalc.css — 세금·수수료 계산기 공용 조각 (xn-ui.css 위에 얹는다)

   쓰는 곳: acquisition_tax_calc · brokerage_fee_calc · gift_tax_calc · vat_calc · rent_tax_credit_calc · car_tax_calc ·
           year_end_tax_calc · capital_gains_tax_calc · income_tax_calc.
   xn-ui 키트에 없는 것만 둔다 — 입력 묶음 제목, 세부 내역 표, '기준값' 접이식 칸, 요건 체크리스트, 계산 예시 상자.
   색은 키트 변수(--accent·--border·--surface-2 …)만 쓴다. 사이트는 --accent / --accent-2 / --grad 만 바꾼다. */
