Summary

• Introduce the official responsive VitePress documentation site with Scarp branding, local search, light/dark themes, TypeScript config and navigation.
• Document only implemented Scarp v0.0.5-alpha.1 syntax/CLI, with explicit prerelease status, installation, learning guides, source modules, numerical primitives, Rust embedding, and limitations.
• Add seven exact source/stdout fixtures copied from the published Scarp release, with 16 verified upstream Git blob IDs and pin the compiler SHA.
• Add documentation link/anchor checks, evidence checks, compiler-backed run/check/tokens CI, and GitHub Pages deployment on main.
• Add README, contribution process, templates, dependabot, and deployment checklist.

Validation performed locally

• npm run check:docs — PASS (29 Markdown pages, 200 link references)
• npm run check:fixtures — PASS (7 cases / 16 Git blob identities)
• YAML/JavaScript syntax checks — PASS
• Full VitePress build and compiler conformance must be confirmed by GitHub Actions because npm registry and Rust toolchain were not available in the local environment.

Review / release gate

Do not merge until GitHub Actions Documentation CI passes. Once green, merge to main to trigger the Pages workflow, and select Settings → Pages → GitHub Actions if the repository has not yet done so. The Scarp compiler and language APIs remain prerelease/experimental.
