+# Project Context
+
+## Concept
+
+Interactive encyclopedia/learning app for the Primal Diet by Aajonus Vonderplanitz.
+
+Graph-like structure as the primary navigation metaphor:
+- Interactive human body map as entry point
+- Body parts/systems → link to ailments
+- Ailments → link to recipes
+- Recipes → link to ingredients
+- Ingredients → link to properties/details
+
+## Content
+
+Sourced from books by Aajonus Vonderplanitz. Curated by the owner only — no community editing, no authoring UI. All data hardcoded or loaded via config files, embedded in the binary at compile time.
+
+## Deployment Targets
+
+- Native executable (all data embedded in binary)
+- Browser via WASM (same codebase, two build targets)
+
+## UX Vision
+
+Game-engine style — custom rendering, animations, smooth transitions, physics-based graph layouts. Not a traditional web UI.
+
+## Tech Stack — Under Consideration
+
+- **Raylib + C++ + Emscripten** — leading candidate. Mature WASM story, true native binary, lean output.
+- **Raylib + Zig** — elegant `@embedFile` for data embedding, but friction between Zig's WASM target and raylib's Emscripten dependency.
+- **Mach (Zig game engine)** — native + WASM via WebGPU, but pre-1.0 and still maturing.
+- ~~Three.js + Electron~~ — discarded. Electron too heavy, sidesteps WASM.
+
+## Constraints
+
+- No widget toolkits — fully custom rendered
+- No authoring UI — content is defined in code or config
+- Same codebase must target both native and WASM
