/* ⭐ V16 UPDATE (FIX LAYOUT OVERLAP — Script tab mobile):
   🎯 VẤN ĐỀ:
     • Trong LOCALSTORAGE → Script (mobile), block "📂 Kịch bản đã lưu"
       bị block "Bước 2: Import kịch bản" đè lên.
     • Input "Tên folder mới" tràn ra ngoài card.
     • Nguyên nhân: .cs-step-flow mobile (grid-template-columns: 1fr)
       không có margin-bottom/padding-bottom → không tách biệt với
       .cs-saved-section. Textarea không có overflow-y → text dài tràn.

   🔧 FIX (CHỈ CSS, không đụng JS):
     1. .cs-step-flow mobile: grid → flex column + padding-bottom +
        border-bottom dashed làm separator.
     2. .cs-import-textarea: thêm overflow-y: auto.
     3. .cs-saved-section: thêm clear: both + position: relative + z-index: 1.
     4. .cs-prompt-collapse-text: giới hạn max-height + overflow-y: auto.

   ✅ CHỈ THÊM rules mới, KHÔNG sửa rules cũ.
   ✅ CHỈ target trong @media ≤ 768px (desktop không ảnh hưởng).
   ✅ 1 file duy nhất — không đụng HTML/JS.

/* ⭐ V15 UPDATE (CLEANUP — QUAY LẠI ĐƠN GIẢN):
/*   🎯 VẤN ĐỀ VỚI V12/V13/V14:
/*     • Tao thêm quá nhiều fix phức tạp (flex-gap reset, margin
/*       explicit cho từng block, breakpoint 360px, !important)
/*     • → Tự phá cái V13 đang chạy tốt (đổi margin-top 2rem → 0)
/*     • → Layout 2 (Import) vẫn cao, 3 nút vẫn bị cắt
/*
/*   🔧 FIX V15 (đơn giản hóa):
/*     1. Base CSS: GIỮ NGUYÊN (không đụng)
/*     2. Media 768px: CHỈ 3 rules
/*        • .cs-import-textarea: max-height 100px (thấp để 3 nút hiện)
/*        • .cs-saved-section: margin-top 24px (tách biệt)
/*        • .cs-step-actions: flex-wrap nowrap (nút xếp ngang)
/*     3. Media 480px: textarea 80px + button nhỏ
/*     4. XÓA media 360px (không cần)
/*
/*   ✅ Logic: Textarea thấp → card Step 2 ngắn → 3 nút hiện
/*     → Saved-section margin-top 24px → không dính
/*
/* ⭐ V14 UPDATE (FIX LAYOUT MOBILE — 1 LẦN ĂN LUÔN):
/*   - Mobile 768px: bỏ flex-gap, dùng margin, force row buttons
/*   - Mobile 480px: vẫn row, button small
/*   - Mobile 360px: button tiny (MỚI)
/*
/* ⭐ V13 UPDATE (FIX LAYOUT MOBILE — tinh chỉnh tiếp):
/*   - Mobile 768px: .cs-saved-section margin-top 2rem, 3 nút xếp ngang
/*   - Mobile 480px: BỎ flex-direction column, giữ row
/*
/* ⭐ V12 UPDATE (FIX LAYOUT MOBILE):
/*   - .cs-container: overflow hidden → visible
/*   - .cs-container > .cs-setup: padding 0 → 0.5rem 0
/*   - Media query mobile: gap, margin, height cho step-flow/card
/*
/* ⭐ V11 (SPEAK BUTTON STATES):
/*   - THÊM 3 state cho nút 🔊 để có visual feedback khi iOS bị stuck:
/*     • .speak-loading  — đang chờ (opacity pulse)
/*     • .speak-speaking — đang phát (scale pulse + accent bg)
/*     • .speak-error    — lỗi / fail (đỏ + shake)
/*   - Áp dụng cho cả .cs-speak-btn và .cs-speak-btn-big
/*   - Keyframes: csSpeakLoading, csSpeakSpeaking, csSpeakError
/*   - Mobile: giảm nhẹ animation intensity (tránh tốn pin iOS)
/*   - Mục đích: user BIẾT click đã được nhận dù audio có phát hay không
/*
/* ⭐ V10 (IPA CHO BETTER_VERSION):
/*   - THÊM style cho block "Câu tự nhiên hơn" trong feedback:
/*     • .cs-better-version           — wrapper chứa text + nút 🔊 🔉
/*     • Override cho .cs-ipa-btn + .cs-sub-ipa bên trong
/*   - Mobile responsive cho better_version block
/* ⭐ V9 (IPA DISPLAY):
/*   - THÊM style cho IPA của câu:
/*     • .cs-sub-ipa          — block hiển thị IPA chính
/*     • .cs-sub-ipa-empty    — variant khi không đủ dữ liệu IPA
/*     • .cs-ipa-btn          — nút toggle IPA cho User bubble
/*     • .cs-ipa-btn:hover / .cs-ipa-btn.active
/*   - Mobile responsive: giảm font-size + padding
/* V14 (SPLIT từ V9.9): Tách thành 2 file                       */
/*   - conversationScript.css     → Core (file này)             */
/*   - conversationScriptChat.css → Chat/Intent/Summary         */
/* V9.3 (FIX NÚT BỊ VÔ HIỆU HÓA):                               */
/*   - FIX #3: .cs-saved-actions dùng visibility thay vì        */
/*             chỉ opacity + pointer-events                     */
/*   - FIX #3: Thêm @media (hover: none) cho tablet/touch       */
/*   - FIX #4: .cs-folder-actions cùng pattern visibility       */
/* V9 (FOLDER + RANDOM):                                        */
