feat: initialize Grav multi-site project

- Add AGENTS.md with project requirements and site inventory
- Add JOURNAL.md for project tracking
- Add etc-hosts-entries.txt for local testing (22 domains)
- Add setup.php for Grav multi-site routing configuration

This project migrates 21 mdbook sites to a single Grav multi-site
installation. Each site will have its own environment directory under
user/env/{fqdn}/ with independent config, pages, and themes.

Development runs in Docker on port 12000 (container: tsysstatic-dev-grav).
Production target: Cloudron Grav app at staticsites.turnsys.com.

+# TSYS Static Sites - Grav Multi-Site Project
+
+## Requirements
+
+### Infrastructure
+- Grav CMS multi-site installation for hosting static content
+- Currently migrating from mdbook-based sites
+- Target production: Cloudron LAMP app at staticsites.turnsys.com
+- Development: Docker container on port 12000, named with prefix `tsysstatic-dev-`
+
+### Source Content
+- 21 mdbook repositories in `/home/charles/Projects/tsysstatic/`
+- Directory name = FQDN for the site
+- All sites use standard mdbook structure (book.toml, src/, SUMMARY.md)
+
+### Multi-Site Strategy
+- Single Grav installation hosting multiple domains
+- Each site can have its own git repository for content (per-site repos preferred)
+- Use Grav's environment-based multi-site feature (user/env/{fqdn}/)
+- Domain-based routing via setup.php
+
+### Sites to Migrate
+1. governance.turnsys.com (substantial content - governance docs)
+2. plan.ap4ap.org
+3. plan.ezeda.org
+4. plan.afabn.org
+5. plan.ezpodstack.org
+6. plan.hfnoc.net
+7. plan.knownelement.com (substantial content - KNEL docs)
+8. plan.meetmorse.com
+9. plan.merchantsofhope.org
+10. plan.rackrental.net
+11. plan.redwfo.com
+12. plan.rwscp.net
+13. plan.sidedoorgroup.org
+14. plan.sol-calc.com
+15. plan.suborbital-systems.com (has chapter content)
+16. plan.teamrental.net
+17. plan.thecampustradingcompany.com
+18. plan.thepeernet.com
+19. plan.turnsys.com
+20. plan.yourdreamnamehere.com
+21. startinglineproductions.com-bizopprodplan (substantial content - STLP plans)
+
+### Development Workflow
+1. Local Docker container for development/testing
+2. /etc/hosts entries for local domain testing
+3. Git repository for Grav configuration and content
+4. Sync to Cloudron Grav instance for production
+
+### Technical Constraints
+- Use only: docker, git, and unix utilities on host
+- No AI/ML tools or language servers for file manipulation
+- Container naming: `tsysstatic-dev-*` prefix
+- Port: 12000

+# Project Journal
+
+## 2026-03-02
+
+### 15:52 - Project Initiated
+- Explored existing mdbook repositories (21 sites found)
+- Researched Grav multi-site capabilities:
+  - Grav supports environment-based multi-site via `user/env/{hostname}/`
+  - Each site can have independent git repository
+  - Domain routing via setup.php or environment variables
+- Researched Grav Docker setup: `getgrav/grav:latest` image
+
+### 15:53 - Requirements Captured
+- Created AGENTS.md with project requirements
+- Container naming convention: `tsysstatic-dev-*`
+- Development port: 12000
+
+### Next Steps
+- [ ] Start Grav Docker container on port 12000
+- [ ] Create /etc/hosts input file for local testing
+- [ ] Configure Grav multi-site structure
+- [ ] Create per-site environment directories
+- [ ] Initialize git repository
