 Bubbletea v1 manages cursor positioning in software ("virtual cursor"). It draws a `█` at the cursor position. The terminal's *real* cursor stays at `(0, 0)`.
 
-This breaks every CJK input method. IME candidate windows (the popup showing 가/각/간 for Korean Hangul composition, kana → kanji for Japanese, pinyin lookup for Chinese) anchor to the terminal's **real** cursor position. With v1, the candidate window appears at top-left while you are typing somewhere in the middle of the screen.
