v0.2.1 — Deploy infrastructure & CI fixes

What's changed

Bug fixes

• CI: typecheck and build jobs now correctly build @chesskernel/shared and run prisma generate before running tsc — CI was failing on every push since v0.1.0
• Docker deploy: fixed multiple issues that made docker compose up non-functional:
  • Build contexts corrected (Dockerfiles expect the monorepo root, not server/)
  • Dockerfile.client referenced docker/nginx/nginx.client.conf which didn't exist — file added
  • Dead client_build volume replaced with a proper client service
  • Migrations now run automatically on server start via docker-entrypoint.sh — no manual exec needed after deploys

New

• Caddy TLS — add DOMAIN=your.domain.com to .env and Caddy handles HTTPS + Let's Encrypt automatically
• .env.example — all required environment variables are now documented

Polish

• README board preview now uses the real cburnett piece SVGs from react-chessboard, matching the home page exactly

Upgrading

git pull
docker compose -f docker/docker-compose.prod.yml up -d --build

Migrations run automatically on start.

v0.2.0 — Analysis UX, material count, classification badges, docs

What's new in v0.2.0

UI Improvements

• Material count — real Cburnett SVG piece icons next to player names, showing captured pieces + +X material advantage
• Classification badges — rebuilt as a standalone SVG overlay; badges always render regardless of arrow state; correct chess.com-scale sizing
• Eval bar — widened to 20px, vertical score label, border for light-theme legibility, pure black/white text
• Illegal move animation — chess.com-style shake + red glow on rejected moves
• Feature carousel — homepage features section redesigned as infinite-scroll ticker; pauses on hover; edge fade masks

Frontend

• Hero tagline ("Open Source · Free Forever") moved to i18n — now translatable in EN/PT/ES
• Removed "Self-Hosted" feature card from homepage
• analysis.description and analysis.starting keys added to all locales (no more hardcoded EN strings on the analysis page)

Infrastructure

• CI pipeline fixed (pnpm version field conflict resolved)
• Stale CJS artifact cleanup in shared/src

Documentation

• All docs updated with Mermaid diagrams (sequence, state machine, ER diagram, flowcharts)
• New: docs/frontend/architecture.md — component tree, data flow, i18n guide
• New: docs/security/security.md — threat model, auth flow, move validation, rate limiting
• README redesigned with centered chess board SVG, badge row (CI/version/license/stars/visitors), marketing copy, quick-start
