Bangla text is taller than Latin text at the same font size, and it wraps differently. A button that fits 'Submit' does not fit its Bangla equivalent, so layouts built English-first break the moment they are translated.
CubieAI was designed the other way around. Every component was laid out with Bangla strings first, then checked in English. Nothing needed shrinking afterwards.
Tone matters as much as layout. A literal translation of confident English marketing copy sounds strange in Bangla. The copy was written separately in each language rather than translated.
The result is a tool Bangla creators use without noticing the language, which is the point. Localisation you can feel is localisation that failed.
