1. Syllable dividers now require CV validation: morphological vertical line detection checks if word_box image actually shows thin isolated pipe lines before applying pyphen. Only first word per cell gets pipes (matching dictionary print layout). 2. Grid editor scroll: changed maxHeight from 80vh to calc(100vh-200px) so editor remains scrollable after edits.
