/* Kohana. build-07 r21 PROTOTYPE (2026-11-03, local, not published) — loaded after build07s.css. CSS only.
   Small, safe refinements found by the whole-page audit (audit_site.py); no layout, text or behaviour changes.
   1. One card standard. The letter cards on tablets / PC now share the review cards' radius, border, shadow and paper colour
      (phones already did since r15); the mahana perk card, the only other framed card, takes the same radius and shadow.
   2. Readability: the hero notes reach 4.5:1 on the hero ivory and are never under 12px; the small line in 「続きを読む」
      (質問①〜⑨への回答) is 12px instead of 11.5px.
   3. Touch: 「注記の詳細を見る」 is 44px tall again (r19 had made it 40px). */
