* The widget keeps a SINGLE copy of the text (the cell content itself, |

* CSS-truncated while collapsed). The previous <details>/<summary> |
| 14 |
* structure duplicated the text (truncated preview + full content), and |
| 15 |
* browser find-in-page searches collapsed content too, so Ctrl+F counted |
| 16 |
