/* ==========================================================================
   SNS ENGINE コラム（/blog/）専用スタイル
   2026-09-19 v3：角丸を全廃し、LPと同じ水準の組版に作り直し。
   Netlify Functions（deployment/lib/blog-render.mjs ほか）が返すHTMLから読み込まれる。
   terms.html は自己完結の<style>でヘッダー・フッターを上書きしているため、
   このファイルの冒頭（本体・ヘッダー・フッター上書き部分）は同じ内容を複製している。
   terms.html の<style>を変更した場合はここも合わせて直すこと。
   ヘッダー・モバイルメニュー・フッターは濃紺のまま。そこから下のページ本体だけ
   白基調に変える（knowledge/BRAND_GUIDE.md 白基調モード準拠）。

   設計ルール（v3）
   - border-radius は原則0。例外は5か所だけ：
     .blog-cta-doc / .blog-cta-trial（LPの資料CTAボタンと同値999pxのピル。
       LPは hero-cta.css が最後に読まれるため、そこが最終値）、
     .blog-material-banner>a（LPの追従バナーと同値14px）、
     .blog-campaign-btn（LPヘッダーの無料トライアルと同じ999pxのピル）、
     .blog-author-avatar（円形50%）。
   - 影・グラデーションは使わない。例外はLPのCTA部品を複製した箇所のみ。
   - オレンジはCTAとPICKUPの点だけ。文字色には使わない。
   - 英字見出し＝Inter 800、和文＝Noto Sans JP。
