/* ============================================================
 * Tiful v4 Onboarding — Common Stylesheet (v1)
 * 2026-05-03 / Phase 5 (CSS 分離)
 * ============================================================
 * 集約画面: 8 画面 (Coachmark は coachmark_v1.css に別出し)
 *   - Hero        (01)        body.ob-hero
 *   - Value       (2a/2b/2c)  body.ob-value
 *   - Signup      (03)        body.ob-signup
 *   - PickIntro   (04)        body.ob-pickintro
 *   - Tifuler     (05)        body.ob-tifuler
 *   - Complete    (06)        body.ob-complete
 *
 * 設計原則:
 *   - 共通土台 (reset / body / iPhone モード) は無 scope
 *   - 画面個別スタイルは body.ob-* で scope して衝突分離
 *   - 元 inline と byte-by-byte 互換 (visual regression なし)
