Standardize icons

[hey-august]

For the new Fern site, DevEx would like an authoritative reference to icons for products, categories, and concepts in use on the docs.

Products

• SWML
• Agents SDK
• Server (formerly the "Realtime" or "RELAY Realtime") SDK
• Browser SDK
• Call Flow Builder
• AI Agent (this is the Dashboard GUI agent builder)
• WireStarter
• SWSH
• Compatibility
  • cXML
  • Compatibility REST API
  • Compatibility Client SDKs

Channels

• Voice
• Messaging
• Video
• Chat
• Fax

Communication paradigms

• Request-driven APIs: REST and JSON-RPC
  • client initiates, gets a response, connection closes)
• Real-time / persistent APIs: RELAY over WebSocket
  • connection stays open, events flow both ways)

Other SignalWire stuff

• Support
• Friday Hangouts
• FreeSWITCH
• Cantina (SignalWire Work)

Concepts

These are sections of the docs that don't necessarily map 1:1 with a specific product, but for which an icon would still be useful:

• RELAY (includes Server and Browser SDKs, and the currently not-exposed RELAY protocol)
• AI (includes SWML ai method, Agents SDK, GUI builder, etc)
• Platform (this is a docs-specific abstraction that encompasses the cloud platform broadly, including the Dashboard)
• The Campaign Registry
• PUC
• Call Fabric
