Bootstrap Design System

Generate two artifacts for the current project in one PR:

1. DESIGN.md at the project root — the portable, framework-agnostic source of truth. Any coding agent (Claude, Codex, Cursor, Copilot) and any stack (React, Vue, Svelte, Astro, vanilla HTML) should be able to read it and produce UI that matches the brand.
2. A visual style-guide page that renders every section of DESIGN.md at real size using the project's own component primitives.

Work the phases in order — do not skip phases.

Phase 0 · Resolve inputs (do this first)

You are not handed placeholders — discover them. Resolve each input below from the project, then apply any overrides the user passed in $ARGUMENTS. Ask the user ONLY for an input you genuinely cannot determine.
