/* =========================================================================
   言文字｜台灣人才聚落・創始會員計畫 — 「邀請函・限量名冊」版型
   範圍：僅 #view-home（hero＋hub 五主題）。其餘內頁沿用 fellow/styles.css。
   命名：本檔新增之版型骨架一律 fnd- 前綴；沿用既有共用類別
   （.wrap/.eyebrow/.btn/.terms-card/.fund/.bar/.hero-letter…）維持相容，
   不更動、不刪除任何 JS 掛鉤（data-buy／data-go／#hero-fund-*／[data-bar]）。
   CIS：本頁唯一黃擊＝主 CTA 購買鈕（.btn-seal，永遠可見）；名額進度
   （.fnd-scarcity）改墨底，因 fund--quiet 會在名額<10 隱藏之，避免 home 無焦點。
