Shared reference for the frontend-web cluster: the rendering-model decision (CSR / SSR / RSC / static) that sets the hydration boundary, plus the conventions every spoke shares — the SSR/'use client' contract, the motion-foundations layering rule, the accessibility baseline, and the framework/tooling matrix. USE WHEN choosing a framework, wiring SSR-sensitive or motion code, or planning accessibility — the interlocking rules every frontend-web spoke depends on.
