2.3.4

[2.3.4] - 2026-07-29

Changed

• Pane border and title visibility: the pane title is now always
  drawn in the same color as its surrounding border, so the focused
  pane's title picks up the active border color instead of a
  tab-bar-oriented color that could vanish on dark backgrounds. The
  unfocused border color was also brightened in all eight built-in
  themes (each theme now uses its palette's "comment" tone), making
  inactive pane frames and titles easier to distinguish without
  overpowering the focused pane.
