   しゅくるithnani 採用LP — v2 完成候補版 スタイルシート
   （v1: css/style.css は変更していません。バックアップ: _backup_v1_20260821/）

   構成：
     1. Design Tokens
     2. Base / Reset
     3. Layout Utilities
     4. Components
        - Progress / Header / Hero(分割型) / Section / Article
        - Fact Grid / Voice Quote / Day Timeline / Info Cards
        - Salary Example / Record Cards / Inline CTA / Photo Band
        - Interview(Q&A) / Dark Section / Letter / Requirements
        - Final CTA / Sticky CTA / Footer
     5. Motion / Reveal
     6. Media Queries

   v1からの主な変更意図：
     - ヒーローを「写真＋コピー」の分割型にし、人物が切れず、文字も写真に埋もれない構成へ
     - 本文を「1文＝1段落」から通常の段落組みへ変更し、スマホ総高を圧縮
     - スタッフ証言を各セクションに置ける c-voice-quote を新設
     - CTAを心理段階別に配置できるよう c-cta-box / c-sticky を新設
     - リビール演出を 1000ms → 450ms に短縮（高速スクロール時の可読性）
     - タップ領域を最低44pxに統一
