Description

Goal: Distinct, consistent heading styles and spacing.

Detailed work:

• Create a Heading helper/component that accepts level ∈ {1, 2, 3}
  • Level 1 → bold bright-white
  • Level 2 → cyan
  • Level 3 → dim white
• In the render pipeline, insert one blank line before every heading
• Refactor existing hard-coded headings to use the helper

Acceptance Criteria

• [x] Unit test confirms correct color/weight per level
• [x] Snapshot shows a blank line before every heading
• [x] No direct screen.program.write calls remain for headings

Implementation Notes

Successfully implemented a comprehensive heading system for consistent visual hierarchy across the terminal UI:

Key Components Created:

• Heading Helper (src/ui/heading.ts): Core component with 3 distinct heading levels
  • Level 1: Bold bright-white for main titles
  • Level 2: Cyan for section headings
  • Level 3: Dim white for subsection labels
• Comprehensive Test Suite (src/test/heading.test.ts): 11 test cases covering all functionality

Refactoring Completed:

• Task Viewer UI (src/ui/task-viewer.ts): Replaced all hard-coded bold headings with proper heading levels
• TUI Components (src/ui/tui.ts): Updated group headings to use Level 2 styling
• Automatic Spacing: All headings now include blank lines before them for better visual separation

Technical Details:

• Blessed tag formatting with proper color codes and bold styling
• Graceful fallback handling when blessed is unavailable
• Consistent spacing implementation across all UI components
• No direct screen.program.write calls found or used

All acceptance criteria have been met with comprehensive test coverage and consistent implementation across the codebase.
