1.4.0

Improved layouts for narrow screens across diagram types:

• Sequence diagrams wrap participant names, messages and notes. Railroad diagrams fold long sequences onto connected rows.
• Journey and event modeling diagrams support vertical layouts. Ishikawa diagrams switch to a vertical cause tree.
• Packet diagrams split fields into shorter rows, preserving bit numbers and labels.
• Tree views wrap filenames and place descriptions beneath them. Architecture, block, C4, quadrant and Wardley diagrams use space more efficiently.
• Swimlanes switch to vertical flows on narrow screens while keeping steps in their lanes.
• Improved swimlane routing to separate handoffs and decision return paths, avoid obstacles, and reduce unnecessary spacing.
• Improved C4 routing around shapes and boundaries, with clearer separation between connections and labels kept beside their arrows.
