Compiler Pipeline

1. Lexer — Unicode‑aware, NFC‑normalized stream with:
   • Line ⍝ and block ⦅ ... ⦆ comments
   • AI‑only blocks ⚡ ... ⛓ (authorization gates)
   • Numeric glyphs 𝍠…𝍩 (0‑9) and ASCII numerals
2. Parser — Builds AST from tokens
3. Semantics — Type checks and validates constructs
4. IR / Lowering — Produces a portable intermediate form
5. Emitters — --emit js or --emit ai
6. Titan — Execution/runtime surface for future native backends

See detailed pages: Lexer, Parser, Semantics, IR & Lowering, Code Generation, AI Emitter, Titan VM.
