[iagommendes]

Summary

Implements Phase 3 — Comunidade e Escala from the architecture roadmap.

3.1 App Desktop (Tauri 2)

• src-tauri/ wrapper around the Vite build
• pnpm tauri:dev / pnpm tauri:build scripts
• GitHub Actions workflow .github/workflows/desktop.yml (Linux build)
• rust-toolchain.toml pins Rust 1.88 for reproducible builds

3.2 Sistema de Temas

• ThemeSchema in @coderkeys/schemas
• 3 built-in themes: default-dark, default-light, dracula
• Settings page: appearance (light/dark/system) + color palette selector
• Dexie migration v2 for colorTheme persistence

3.3 Contribuição Automatizada

• CONTRIBUTING.md + docs (ADDING-LOCALE, ADDING-THEME, ADDING-TRACK)
• GitHub Issue Forms (new lesson, new locale)
• PR template with content checklist
• Content preview bot on PRs (.github/workflows/content-preview.yml)

3.4 Novos Tracks

• devops — Docker, kubectl, Terraform, shell
• data-science — Python, SQL, pandas, numpy
• legal-translators — bilingual legal vocabulary
• 60 lessons total (en-US + pt-BR)

3.5 Internacionalização

• es-ES UI locale (full i18n parity)
• Track metadata in es-ES
• RTL CSS readiness ([dir='rtl'] rules)

3.6 Performance e Qualidade

• Playwright E2E: catalog → lesson → complete flow
• Engine benchmark test (< 1ms per keystroke)
• CI job for E2E tests
• Fix: Enter key maps to \n in lesson sessions

Verification

pnpm typecheck
pnpm test
pnpm validate-content   # 60 lessons
pnpm check-i18n         # en-US, pt-BR, es-ES
pnpm build
pnpm test:e2e
pnpm tauri:build        # requires Rust 1.88+

Phase 3 completion criteria

• Desktop app (Tauri)
• Contribution documentation
• 50+ lessons in 2 languages (60 lessons, en-US + pt-BR)
