Practical Logistics 4 - Foundations

with 0.0.1a recorded as frozen, the next display/GSI parity work needs to make common editor workflows faster without weakening the existing server-side layout validation.

What changed

• Adds additive Shift-click multi-selection with visible selection outlines.
• Adds atomic revision-fenced deletion for multi-selection.
• Adds local Ctrl+C/Ctrl+V copy and paste for typed display elements, preserving styles and applying a deterministic offset.
• Keeps Ctrl+D as a duplicate compatibility shortcut.
• Updates the 0.0.2a roadmap and documents the editor behavior.
