/* ==========================================================================
   GROVYN — Blog Footer CTA 三卡片改版 + 彈窗（2026-05-27）
   依賴：blog-single.css（.cta-block / .cta-title / .cta-sub / .cta-link 基底）
        sensory-tokens.css / ts-tokens.css（--ts-* tokens）
        grovyn-login-dropdown.css（註冊卡 .grovyn-login-card 視覺，本檔只加置中外殼）
   命名空間 .bcta-* 與 .cta-social/.cta-member/.cta-about，避免干擾頁首登入系統。
   深色：body.grovyn-dark-mode（與 blog-shared.css 一致）。
