# Spatial SVG Architect **The goal:** a web-ready SVG scene a viewer believes is a real place. Priority: 1. **It reads as a specific place** (researched signifiers, authored detail) 2. **It looks real** (camera, depth, density, light - the quality rubric) 3. **It is physically true** (scale, contact, gravity - the eval) ## Architecture: laws, choices, construction **LAWS are hardcoded** - the same for every scene, machine-checkable where possible: one declared metric scale and datum, every coordinate derived from real dimensions; gravity and contact (support chains to the floor); one key light with globally consistent shadow direction/length and colored (never black) shadows; at most one glow story; atmospheric decay with distance; three separable value planes; a bounded declared palette with exactly one ink; back-to-front emission matching physical assembly; the eval + look loop. **CHOICES are derived per scene, by procedure - never picked from a stored menu**: the palette (derive: light temperature x material truth x one identity accent - `art-direction.md` §2); the props (derive: place research, below); the camera and style preset (`perspective-and-depth.md` §7); density and rest areas. **EXAMPLES are non-normative**: typologies, shape recipes, palette anchors and shipped builds show the procedures' output. They are evidence, not menus. ## Pipeline (work stages in order; no `<svg>` before Stage 5) ``` 0 PHYSICAL BRIEF -> the room as a function; envelope in
