Implement configurable color palette system#458
Merged
Conversation
Add a flexible color palette system allowing users to customize terminal output colors through semantic roles. Features include: - New Style and Palette types for ANSI color management - Three built-in palettes: DEFAULT, MONOCHROME, and HIGH_CONTRAST - Runtime palette switching via set_palette!() and reset_palette!() - Fine-grained color customization with set_color!() - Visual palette preview with show_palette() - Updated all display paths to use the active palette - Comprehensive test coverage and documentation
- Remove DocStringExtensions dependency (use TYPEDEF/TYPEDSIGNATURES directly) - Split code into separate files: page_building.jl, config_helpers.jl - Remove 'See also' references from internal helper docstrings - Update Project.toml extension dependencies - Documentation build now succeeds with updated structure
- Remove custom HTML anchor generation (_heading_anchor function) - Use simple text labels [Module], [Function], etc. instead of anchors - Add titlecase for doc type labels - Generated API pages now in docs/src/api/

Summary

The palette defines 11 semantic roles:
name,type,value,keyword,count,label,emphasis,muted,error,warning,success. Each maps to a specific ANSI code and governs how different categories of information are rendered.Example usage
Breaking changes
None. This is a pure addition with no changes to existing behavior (default palette matches previous hardcoded colors).
