/* JK Game DOS Arcade — 站台樣式（2026-09-17 重整）
 *
 * 三套字體、三個崗位，不互相搶：
 *   --font-ui    Noto Sans TC   所有內文、按鍵、導覽、標題。一個 7 級尺度（11–24px）＋ display。
 *   --font-pixel Press Start 2P 只做「標籤」：品牌名、卡片小標、eyebrow、數字。最小 10px，永不進按鍵。
 *   --font-term  VT323          只在 CRT 螢幕與跑馬燈裡，最小 19px（它的 x-height 很矮）。
 * 之前 19 種字體×字級組合、Press Start 2P 壓到 7px、VT323 混中文字退回 Noto 造成大小不一，
 * 全部收回到這裡的變數。按鍵只有一套（.btn / .btn-ghost / .btn-sm / .btn-danger）。 */
