📋 Decision Context

Question:

Session 133: What new reusable NX libraries were created and why?

Task: Not specified

🎯 Decision Made

Chosen:

Build 3 custom zero-dependency NX libraries

Options Considered:

1. Use external dependencies (marked, highlight.js, emoji-mart)
2. Build 3 custom zero-dependency NX libraries

💭 Reasoning

Created 3 new @libs-ux libraries with zero external runtime dependencies: (1) @libs-ux/ux-code-highlight (16 files) -- Token-based syntax highlighter with 9 language grammars (TS, HTML, CSS, JSON, Bash, Python, SQL, YAML, Markdown), ~50 lines per grammar. Theme-aware via --ux-code-* CSS variables. UxCodeBlockComponent with line numbers, copy button, language badge. (2) @libs-ux/ux-markdown (10 files) -- Custom markdown-to-HTML parser supporting headings, bold/italic/strikethrough, code blocks (delegates to ux-code-highlight), lists, links, blockquotes, tables, images, task lists. MarkdownSanitizerService strips XSS vectors (script tags, event handlers, javascript: URLs). UxMarkdownComponent + UxMarkdownInlineComponent. (3) @libs-ux/ux-emoji-reactions (17 files) -- EmojiRegistryService with ~200 Unicode emoji across 9 categories, search, recent tracking (localStorage). UxEmojiPickerComponent, UxReactionBarComponent, UxReactionPickerComponent (quick 6-preset), UxStickerGridComponent (integrates with @libs-ux/ux-icons sticker category). ReactionService for immutable reaction state management. All libraries use --ux-* theme variables, BEM CSS, standalone Angular components with signal APIs. Total: 43 files, ~2,600 lines. Reusable beyond chat (docs, comments, annotations, code editors).
