🎉 Version 2.2

Changed

• GitHub Pages hero now uses an animated image instead of the live app. Both
  docs/index.html and docs/app.html replace the embedded live navigator iframe with a
  self-contained animated SVG (docs/assets/srs-chain.svg). Its CSS keyframes build the
  traceability chain in the methodology's causal order: Customer Problems appear first,
  then the Customer Needs that address them, then the Functional / Non-Functional
  Requirements that satisfy them, with links drawing in. The image reuses the real
  navigator's node colors and Phosphor icons, and honors prefers-reduced-motion.

Added

• scripts/build-chain-animation.mjs: generator for the animated SVG. Node colors and
  icons are sampled verbatim from the extension's renderer.mjs, and the chain uses a real
  slice of the bundled CRM demo spec. The canvas app itself is unchanged.

Removed

• docs/navigator-embed.html and scripts/build-navigator-embed.mjs (the live-app embed),
  superseded by the animated image.
