What is inside

• 100 lessons across 16 tracks and 5 phases (Foundations → The Craft → Power User → Builder → Operator).
• 6 interactive labs — a temperature sampler, a tokenizer, a model chooser, a unit-economics/caching calculator, an agent-loop stepper, and a pricing comparator. You move the levers yourself.
• 15 inline diagrams — next-token prediction, the context window, the model family, the agent loop, MCP wiring, the lethal trifecta, tool-use, caching economics, and more.
• 215-term glossary that also powers the dotted-underline tooltips inside every lesson (first occurrence of each term is linked automatically).
• 14 cheat sheets — one dense, printable card per track, two-way linked to the tracks.
• 29 interview questions (easy / medium / hard) with full model answers — the kind asked in AI-native job interviews and by paying clients.
• Flashcards with a Leitner spaced-repetition schedule (1 / 3 / 7 / 21 / 60 days).
• Read-aloud (Listen button), a command palette search (Ctrl/⌘-K), a progress ring, streaks, and a phase-by-phase roadmap.

Every lesson follows the same deep structure: a one-breath summary, a hook, teaching sections, a narrated worked example, a "do it for real" lab, common mistakes, a self-check quiz, graduated practice (warm-up / transfer / stretch), a pocket recap, a spaced-review callback, and a deep-dive for the curious.

Phases D and E include hands-on money content and five portfolio-grade **capstones**: a personal automation suite, a client-ready document pipeline, an MCP server, a deployable API micro-product, and a 30-day income launch
