# Gasser Website session notes

This reference captures reusable implementation details from a session building a new website for a regional construction company.

## Context

The user wanted a modern, professional, Git-maintained website for a construction company, with:

- priority services: customer works and renovations/renovations in existing buildings
- target audiences: private customers first, architects second
- primary conversion: email contact, with phone/form as secondary options
- local SEO: Windisch, Hausen, Brugg, nearby Aargau region
- brand direction: bordeaux logo color + exposed concrete/material feel + anthracite
- trust tone: quality, personal support, reliability, “we take care of it,” not cheap positioning
- subtle Three.js, possibly animated logo/page transitions

## Durable workflow lessons

### 1. Make the site reviewable early

For iterative website work, start and keep the dev server available when the user wants to check progress on PC/mobile:

```bash
npm run dev -- --host 0.0.0.0
hostname -I | awk '{print $1}'
ss -ltnp | grep ':4321'
curl -I http://127.0.0.1:4321/
```

If an old process is bound to `127.0.0.1`, restart the server bound to `0.0.0.0`. Share `http://<local-ip>:4321/`. If mobile fails, offer a tunnel; do not assume the app is broken.

### 2. Astro content collections changed in newer versions

A scaffold with current Astro may reject legacy `src/content/config.ts` with `LegacyContentConfigError`. Use:

- `src/content.config.ts`
- `import { glob } from 'astro/loaders'`
- `loader: glob({ pattern: '**/*.md', base: './src/content/<collection>' })`

With this loader, entries use `entry.id` for route params/links rather than `entry.slug`.

### 3. Browser QA can catch stale dev-server state

After adding content collections, the HTML/build may contain cards while the browser still shows a stale dev-server state. Restart the Astro dev server and reload with a cache-busting query before concluding the component failed.

### 4. Three.js logo enhancement pattern

A good first implementation for a serious company site:

- normal PNG logo fallback as `<img>`
- `<canvas>` overlay/enhancement
- `await import('three')` inside initializer
- texture mapped to a plane
- very small pointer-driven rotation
- subtle brand accent line
- `prefers-reduced-motion` returns early
- `data-three-ready` hides fallback only after texture load
- dispose renderer/materials/geometries on teardown/page swap

Do not let animation dominate the brand. For a construction/company website, the Three.js effect should read as precision and polish, not as entertainment.

### 5. Content model for references

Useful case-study fields:

```yaml
title:
category: Kundenarbeiten | Umbauten | Neubauten | Sanierungen | Baumeisterarbeiten
audience: [Privatkundschaft, Architekten]
location:
year:
services: []
architect:
summary:
heroImage:
gallery: []
featured: true
```

This supports both homepage featured cards and detail pages while staying easy to maintain through Git.
