The container-row tree-prefix used text box-drawing glyphs (├ └ │) positioned with `top: 0.6em` — a single text-line tall. Once rows grew past one line (5em square icon + multi-line body), the `│` columns of consecutive siblings no longer touched, leaving visible breaks in the tree. Replace the text-glyph string with structured DOM: one `.tree-lane` per depth column. Continuation lanes (`.lane-line`) paint a 1px border-left spanning the full row height + the `.containers` gap below, so adjacent siblings' bars visually merge into one unbroken vertical. The row's own joint lane is `├` (branch — bar continues below) or `└` (last — bar stops at icon midline), with a horizontal stub at 3.1em (row padding-top + icon half-height) reaching to the icon edge. Joint y / stub width are derived from the 5em icon + 0.6em row padding-top + 0.8em row padding-left so they meet the icon cleanly. |
