 ' === Legend/Notes === 
 note right of linode_vps 
   • Single point of failure 
   • Minimal functional phase 
   • Limited budget constraints 
 end note 

 note right of titan 
   • IMAP: imap.titan.email 
   • SMTP: smtp.titan.email 
   • Requires manual config 
 end note 

 note bottom of security 
   • KeePassXC database 
   • Sync via WebDAV 
   • Currently self-signed cert 
 end note

 AI Request (TODO - find a way to standardize AI prompts): 

 Help me create a PlantUML diagram to reflect the current status of the architecture for Kusala Tech. 

 Context: 

 - name.com for NS (kusala.studio) 
 - email on Titan Mail (service of name.com) 

   - imap.titan.email 
   - smtp.titan.email 
   - NOTE: they need to be configured manually (autodiscovery does not currently work - ref for configuration can be found at: https://support.titan.email/hc/en-us/articles/900000215446-Configure-Titan-on-other-apps-using-IMAP-POP) 
 - Linode VPS (foss-dev) 

   - Note: this is a single point of failure, but there is not anything currently highly critical, and we are in minimal functional phase with limited to no budget. 
   - Docker 

     - Traefik 
     - Redmine 
     - Certbot will be configured for TLS 
 - KeepassXC for password management 

   - Sync over WebDAV 

     - Tested - works nicely (currently self-signed cert) 
 - Linode LKS (for later migration if necessary)
