## Agent Brief

### Stack
- Static HTML page with one stylesheet and a small vanilla JavaScript enhancement hook.
- No build tooling, dependencies, or framework are present.
- Visual reference: `docs/design-reference.png` (non-authoritative; use the original prompt and existing HTML/CSS as the source of truth).

### Existing work
- `index.html` contains the page structure and visible hero content.
- `style.css` provides the page layout, typography, colors, responsive behavior, and spacing.
- `app.js` sets `document.documentElement.dataset.ready = "true"` after DOM readiness; it does not provide primary rendering or user interaction.
- `README.md` documents the files and direct browser opening.

### Constraints and preservation guidance
- Preserve the intentionally tiny, single-page scope.
- Keep the centered typographic hero, warm white background, near-black serif heading, muted gray supporting copy, and short ochre divider.
- Preserve semantic HTML and keep the visible heading/supporting text in the markup rather than generating it with JavaScript.
- Keep JavaScript minimal; do not introduce a framework, build system, or unnecessary interactions.
- Treat `docs/design-reference.png` as visual guidance only, not as a replacement for the supplied prompt or current target files.

### Blockers and caveats
- No missing renderer or event loop is required: the browser is the renderer and `DOMContentLoaded` is the only lifecycle hook used.
- The supplied files were not executed during this handoff, so runtime behavior and visual fidelity have not been independently verified.
- There is no primary interactive behavior beyond page loading and the optional `data-ready` attribute enhancement.
- Any further visual tuning should be checked in a browser against the design brief and reference image.

## Visual handoff
VISUAL HANDOFF:
- Design reference: `docs/design-reference.png`. It is non-authoritative visual guidance; the user prompt and runnable target remain authoritative.
- Design brief: Create a tiny, elegant one-page static site with a centered typographic hero. Use a warm white background, near-black serif heading, muted gray supporting copy, and a short ochre divider. Keep the layout spacious, responsive, and intentionally minimal. The page should render the heading and supporting text directly in semantic HTML, with the stylesheet handling all visual presentation; JavaScript should remain a thin entry point with only a minimal enhancement or no-op initialization.
