SHELEG Design

Overview

A page feels cinematic not from many animations, but from a single source of truth (measured scroll position) driving many cheap, layered, independently-degradable responses. Centralize scroll into one store; layers read it per frame and react in their own language. Nothing crossfades — things redeploy. Every layer degrades to a calm static state.

REQUIRED REFERENCE — for the cinematic path: read SHELEG_DESIGN.md before implementing a scroll-driven page — architecture, morph math, the DOM↔WebGL bridge, the build recipe (§11), the file map. Product-UI work does not owe this read; the one rule it would owe is repeated here: where a pack's motion tokens differ from the SHELEG defaults, the pack wins.
