+## Dropdown Hairline On 4-Item Enums
+
+Status: Deferred for later polish.
+
+Context:
+- In the 4-item enum case, the dropdown should behave like a no-scroll variant.
+- The major scrollbar behavior is already correct: no active scrolling is needed until there are 5 or more choices.
+- A very thin black vertical line can still appear at the right edge of the opened 4-item dropdown.
+
+What was verified on 2026-03-30:
+- Cheat Engine inspection showed the scrollbar subtree is effectively collapsed in the 4-item case.
+- `btnDec` and `btnInc` were collapsed.
+- `btnPgUp` and `btnPgDn` were not acting like a visible scrollbar lane.
+- The cloned dropdown item widgets were already using the narrow content width.
+- The remaining artifact appears to come from native dropdown/listbox root behavior, not from the populated item text path.
+
+Current code assumptions:
+- Scrollbar visibility is controlled by `choiceCount > 4` in `src/UiInterop.cpp`.
+- For 4 or fewer choices, the code hides the scrollbar and narrows the no-scroll listbox root/content geometry.
+- This fixed the major width mismatch, but not the last hairline seam.
+
+Likely follow-up when revisiting:
+- Compare against a native in-game dropdown that opens with exactly 4 visible rows, if one can be found.
+- Inspect whether the line is a border/separator from the listbox root Presentation rather than a true scrollbar child.
+- If needed, adjust the no-scroll listbox root styling/state separately from the scrollbar subtree.
