feat: initialize Hugo static site with Bootstrap 5.x

Initialize minimal Hugo site structure with Bootstrap 5.3.2 integration for
markusgraf.ch conversion. Implements OpenSpec proposal add-minimal-hugo-site.

Features:
- Hugo project structure with standard directories
- Base layout template (baseof.html) with Bootstrap 5.3.2 via CDN
- Homepage (index.html) and single page (single.html) templates
- Reusable partials: header, footer, navigation
- Responsive Bootstrap grid layout
- Mobile-first design with semantic HTML5
- Valid HTML output with basic accessibility features
- Taxonomies disabled for minimal site (see docs/TAXONOMIES.md)

Documentation:
- IMPLEMENTATION_SUMMARY.md - Complete implementation guide
- docs/TAXONOMIES.md - Guide for re-enabling categories/tags
- static/README.md - Guide for placing static assets

Configuration:
- hugo.toml configured for markusgraf.ch
- .gitignore for Hugo build artifacts

All 24 tasks from OpenSpec proposal completed successfully.

## Context
Converting an existing static HTML website (markusgraf.ch) to Hugo to enable template-based content management. The current site uses Bootstrap for styling, which will be preserved and upgraded to Bootstrap 5.x. This is a greenfield Hugo implementation with no existing templating infrastructure.
## Goals / Non-Goals
### Goals
- Create a maintainable Hugo project structure
- Preserve current website content and design
- Enable easy content updates through templates
- Establish foundation for future CV and blog sections
- Upgrade Bootstrap to latest 5.x version
### Non-Goals
- Redesigning the website appearance
- Adding new content sections (CV, blog) in this change
- Implementing JavaScript features
- Setting up automated deployment pipelines
- SEO optimization
## Decisions
### Hugo Configuration Format
**Decision**: Use `hugo.toml` (TOML format) for configuration.
**Rationale**: TOML is Hugo's default and most commonly used format, providing good readability for simple configurations.
**Alternatives considered**:
- YAML: More verbose for simple configs, but we'll keep it as an option if complex nested structures are needed later
- JSON: Less human-readable for configuration files
### Bootstrap Integration Method
**Decision**: Use CDN links for Bootstrap CSS in the base layout template.
**Rationale**:
- Simplest approach for static site
- No build process needed for CSS
- Fast loading via CDN
- Easy to upgrade versions
**Alternatives considered**:
- Local Bootstrap files: Adds unnecessary files to repository
- Hugo Pipes with SCSS: Overkill for current needs (no custom SCSS)
- npm integration: Unnecessary complexity without JavaScript build needs
### Template Organization
**Decision**: Use standard Hugo template hierarchy with baseof.html and minimal partials.
**Rationale**:
- Follows Hugo best practices
- Keeps templates DRY (Don't Repeat Yourself)
- Makes future extensions straightforward
- Header, footer, and nav are natural partial candidates
**Structure**:
```
layouts/
├── _default/
│ ├── baseof.html # Base template with Bootstrap integration
│ ├── single.html # Single page template
│ └── list.html # List template (future blog)
├── index.html # Homepage template
└── partials/
├── header.html # Site header with nav
├── footer.html # Site footer
└── nav.html # Navigation menu
```
### Content Structure
**Decision**: Start with simple markdown files in `/content` directory, one file per page.
**Rationale**:
- Simple and sufficient for current needs
- Easy to understand and maintain
- Can evolve to page bundles when needed for CV/blog
## Risks / Trade-offs
### Risk: Bootstrap CDN Availability
**Mitigation**: Use well-established CDN (jsDelivr or official Bootstrap CDN) with high uptime. Can switch to local files later if needed.
### Risk: Content Migration Accuracy
**Mitigation**: Manual review of each page after conversion. Keep reference to original HTML during development.
### Trade-off: CDN vs Local Assets
**Chosen**: CDN for simplicity and performance
**Trade-off**: Slight dependency on external service, but acceptable for personal site
## Migration Plan
### Phase 1: Setup (Tasks 1.1-1.3)
1. Run `hugo new site` to scaffold structure
2. Create and configure hugo.toml
3. Verify directory structure
### Phase 2: Templates (Tasks 2.1-3.3)
1. Build baseof.html with Bootstrap CDN links
2. Create homepage template based on current site
3. Create reusable partials
4. Test template rendering with placeholder content
### Phase 3: Content (Tasks 5.1-5.3)
1. Review and document current site structure
2. Create markdown content files
3. Copy static assets to `/static` directory
### Phase 4: Validation (Tasks 6.1-6.5)
1. Build site with `hugo`
2. Run local server with `hugo server`
3. Test all pages and responsive behavior
4. Validate HTML and accessibility
### Rollback
If Hugo migration fails or is unsatisfactory:
- Original static HTML is preserved separately
- Can revert to static hosting immediately
- No database or external dependencies to roll back
## Open Questions
None at this time. Implementation is straightforward following Hugo conventions.

## Why
The current markusgraf.ch website uses static HTML files. Converting to Hugo will provide a maintainable template-based structure that simplifies future content updates and enables easy addition of new sections (CV, blog) without duplicating code.
## What Changes
- Initialize Hugo project structure with standard directories
- Create base layout template with Bootstrap 5.x integration
- Set up reusable partials (header, footer, navigation)
- Convert existing HTML content to Hugo templates
- Configure Hugo site settings
- Add static assets from current website
## Impact
- Affected specs: hugo-site (new capability)
- Affected code: This is a greenfield implementation - no existing code affected
- Migration: Current static HTML will be referenced to recreate in Hugo templates
