v0.1.1 - Bootstrap frontend rendering via Twig templates
All checks were successful
Create Release Package / PHP Lint (push) Successful in 49s
Create Release Package / Build Release (push) Successful in 1m18s

Replace FSE block markup on the frontend with proper Bootstrap 5 HTML
rendered through Twig templates. The Site Editor remains functional for
admin editing while the public site outputs Bootstrap navbar, cards,
pagination, grid layout, and responsive components.

New PHP classes: TemplateController, ContextBuilder, NavWalker
New Twig templates: 20 files (base, pages, partials, components)
Enhanced TwigService with WordPress functions and globals

## Development
### Prerequisites
@@ -48,33 +53,86 @@ npm run build
| Command | Description |
| --- | --- |
| `npm run build` | Compile SCSS, minify CSS, copy Bootstrap JS |
| `npm run build` | Full production build (copy JS, compile SCSS, minify CSS) |
| `npm run dev` | Watch SCSS files and recompile on changes |
| `npm run scss` | Compile SCSS only |
| `npm run postcss` | Minify CSS with Autoprefixer |
| `composer install` | Install PHP dependencies |
| `npm run postcss` | Minify CSS with Autoprefixer and cssnano |
| `composer install` | Install PHP dependencies (Twig) |
### Build Pipeline
1. `copy:js` -- Copy Bootstrap JS bundle from `node_modules` to `assets/js/`
2. `copy:theme-js` -- Copy theme JS (dark-mode.js) from `src/js/` to `assets/js/`
3. `scss` -- Compile SCSS (`src/scss/`) to CSS (`assets/css/`)
4. `postcss` -- Autoprefixer + cssnano minification to `assets/css/style.min.css`
## Architecture
### Frontend Rendering
The theme uses a dual-rendering approach:
- **Site Editor (admin):** FSE block templates in `templates/` and `parts/` for visual editing
- **Frontend (public):** Twig templates in `views/` render Bootstrap 5 HTML via the `template_redirect` hook
The `TemplateController` intercepts frontend requests and renders the appropriate Twig template with data gathered by `ContextBuilder`. FSE templates remain untouched for the WordPress admin editor.
### Key PHP Classes
| Class | Purpose |
| --- | --- |
| `TwigService` | Singleton Twig environment with WordPress functions and globals |
| `TemplateController` | Hooks `template_redirect`, resolves and renders Twig templates |
| `ContextBuilder` | Gathers WordPress data (posts, menus, pagination, comments, sidebar) |
| `NavWalker` | Converts flat menu items to nested tree for Bootstrap dropdowns |
### Navigation Menus
Register menus in **Appearance > Menus**:
- **Primary Navigation** -- Displayed in the Bootstrap navbar with dropdown support
- **Footer Navigation** -- Displayed in the footer
If no menu is assigned, the primary location falls back to listing published pages.
