+**Specified 2026-08-09.** The user's answer was that the grid is wrong for the
+WHOLE left pane, not only for reply rows, which is wider than any of the four
+directions above. Threads and replies both become cards in a single column, with
+no column grid at all. The design is at

+this entry, which records only the finding.

+Two things settled here that the directions above got wrong. Direction 2's `Re:`
+prefix removal is folded in rather than tried first, since the grid goes anyway.
+And the constraint about the tag strip inverts: the strip is not something the
+design has to answer for, it is deleted, because `ThreadListView` exists ONLY to
+paint across columns that no longer exist. This item is a net removal of code.

+**Item 51 is resolved by this design as a side effect** and should not be worked
+separately. Cards are exactly viewport width, so the pane has no horizontal
+scroll range for a click to scroll into.
