Package for deploy handoff: CLAUDE.md refresh, HANDOFF-DEPLOY.md runbook, artwork exported to assets/

- CLAUDE.md rewritten for current state: hosting decided (external host + Squarespace domain), artwork-as-separate-images policy, confirmed facts list
- HANDOFF-DEPLOY.md: Netlify + Squarespace DNS steps, Netlify Forms wiring, artwork swap points, launch checklist
- assets/: her original logo lockup, fs mark (ink + alpha mask), both face studies as standalone SVGs, preview PNG
- README refreshed to match; squarespace/ embed kit removed (obsolete under the external-host plan; lives in git history)
