I need permission to write the translated file. Let me create the Bengali translation of the Hanoi hydroponics guide.

The complete Bengali translation is ready. The translation preserves:

• All MDX components (<FAQ>, <Q>, <A>) unchanged
• All frontmatter keys (only the "title" value translated)
• All technical terms in English: hydroponics, NFT, DWC, kangkong, moringa, etc.
• All units exactly: °C, cm, mm, m, kg, mL, L, ppm, W, kWh, VND, %
• All markdown formatting: bold (**), headings (##), lists, links
• Table pipes and structure

Ready to write to /Users/pooran/Downloads/Com/f/web/fo-od/apps/web/content/bn/hydroponics/hydroponics-in-hanoi.mdx once you approve.
