## Overview

1. **Repository shape**
   - This is a very small, static front-end repository.
   - The core application surface is just `index.html` and `style.css`.
   - There are no visible JavaScript files, backend services, package manifests, or data stores in the tree.

2. **Primary runtime model**
   - The app is meant to run directly in a browser as a static document.
   - `index.html` is the entry point and `style.css` provides presentation.
   - Architecture-wise, the browser is both the rendering engine and the runtime.

3. **Presentation layer**
   - `index.html` likely contains the structural content and semantic markup.
   - `style.css` is the only dedicated asset shown, so all visual design and layout concerns are centralized there.
   - Any interactivity, if present at all, would have to be embedded in the HTML or absent entirely.

4. **Content-to-style dependency**
   - The main data flow is from HTML markup to CSS styling in the browser.
   - There is no evidence of client-side state management, API fetching, or templating layers.
   - This makes the architecture essentially content plus styling, not an application with multiple runtime subsystems.

5. **Build and delivery**
   - The `.github/workflows/static.yml` file indicates automated GitHub Actions usage.
   - That workflow is likely responsible for validation and/or deployment of the static site.
   - The deployment target is not shown, but the workflow is the only visible infrastructure boundary.

6. **CI/CD boundary**
   - The GitHub Actions workflow is the only explicit automation layer in the repo.
   - Any diagram should show a separation between source files in the repository and the workflow-driven publish step.
   - If deployment occurs, it is probably to a static hosting target rather than an application server.

7. **No backend boundary**
   - There are no server-side source files, databases, queue systems, or API definitions.
   - The repo therefore has no internal service-to-service communication path.
   - All logic appears to be pushed to the client/browser or omitted.

8. **No dependency management layer**
   - The tree does not show `package.json`, lockfiles, or build tooling config.
   - That suggests the project may avoid a bundler/build pipeline and rely on raw HTML/CSS.
   - If a build exists, it is not represented in the visible file set.

9. **Operational simplicity**
   - Operationally, the repo is low-complexity: source control, static assets, and one workflow.
   - The main lifecycle is edit files locally, commit to GitHub, then let Actions process the static site.
   - There is no evidence of runtime scaling, environment variables, or secrets management.

10. **What to draw in an architecture diagram**
   - Draw a browser consuming `index.html` and `style.css`.
   - Draw GitHub repository storage as the source of truth.
   - Draw GitHub Actions as the automation boundary between repo contents and any static publishing target.
   - Do not add backend boxes, databases, or API calls unless confirmed elsewhere.

11. **Confidence note**
   - Because the README is empty and there are no other code files, the architecture can only be described at a high level.
   - The repo is best characterized as a static site with GitHub Actions-based automation.

## Components

### Source

Repository content and primary static assets

- **Repo**: git source · Source of truth for the site and workflow
- [index.html](https://github.com/h30s/h30s/blob/main/index.html): entry document · Main HTML entry point and page structure · `index.html`
- [style.css](https://github.com/h30s/h30s/blob/main/style.css): stylesheet · Central presentation and layout rules · `style.css`
- [README](https://github.com/h30s/h30s/blob/main/README.md): project note · Top-level repository documentation · `README.md`

### Runtime

Browser-side rendering surface

- **Browser**: static runtime · Renders the document and applies styles

### Automation

GitHub Actions workflow boundary

- [Actions](https://github.com/h30s/h30s/blob/main/.github/workflows/static.yml): ci workflow · Automates validation and static publishing · `.github/workflows/static.yml`
- **Static host**: publish target · Destination for the generated or deployed site
