Analysis shows that English, Spanish, French are all complete.

Czech is only 40% complete.
✅ Title and intro are translated
⚠️ Step 1: Only partially translated (step1_text2 in English)
❌ Steps 2-3: Completely in English (step2_subtitle, step2_text, step2_video, step3_subtitle, step3_text)
❌ FAQ: Most questions and answers still in English
❌ PDF filename: Still uses English version (Validating_Data_EN.pdf)
