Parser improvements: - Added expression statement fallback in parse_statement() for flexible syntax - Fixed ternary operator to use PeekExpr instead of If AST (better lowering) - Added peek_token() check to avoid ?/?: operator conflicts LLVM Python improvements: - Added optional ESC_JSON_FIX environment flag for string concatenation - Improved PHI generation with better default handling - Enhanced substring tracking for esc_json pattern Documentation updates: - Updated language guide with peek expression examples - Added box theory diagrams to Phase 15 planning - Clarified peek vs when syntax differences These changes enable cleaner parser implementation for self-hosting, especially for handling digit conversion with peek expressions instead of 19-line if-else chains. 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>

Navigation tips
- The “reference/language/LANGUAGE_REFERENCE_2025.md” is the canonical long‑form reference; use the Cheat Sheet for quick syntax lookup.
- Phase 12.7 files capture the finalized sugar and new constructs (peek, ternary, null‑safe).
