Description

Implement TUI pane layout engine with focus management and keyboard-driven navigation.

Development Tasks (☿ Nova)

  • Create layout/ module with grid-based pane manager
  • Implement focus ring visualization (cyan border on active)
  • Add pane splitting: horizontal Ctrl+\ / vertical Ctrl+-
  • Keyboard nav: Ctrl+hjkl moves between panes
  • Pane closing with intelligent merge logic

Testing Criteria (☿ Nova)

  • Resize test: 4-pane layout survives rapid terminal resize
  • Focus visibility test: active pane clearly distinguished
  • Split ratio test: splits create 50/50, then 33/33/33
  • Close merge test: closing middle pane merges neighbors logically
  • Edge case: cannot split below minimum size (10 cols x 3 rows)

Completion Criteria (🜔 Claudian Review)

  • Pane borders render consistently across all themes
  • Minimum pane size enforced (10x3) - splits refused if too small
  • Focus changes propagate to widget (widget knows if focused)
  • Documented: docs/layout.md describes pane system

Blockers

  • #1 (Calendar Widget) - needs widget to contain in pane
  • #3 (Command Dispatcher) - pane operations via commands
