Presets

Preset map

Presets let the server choose between several render paths without changing the client code.

{
  "fallback": "default",
  "presets": {
    "default": "#site-main",
    "sidebar": "#site-main@innerHTML->#sidebar@innerHTML"
  }
}

Header driven

The runtime can read `Recyclr-Use-Presets` and `Recyclr-Event` from the response, which keeps routing logic near the server route that knows the context and lets the server describe alternate swap shapes or follow-up UI events.

Preset triggers can also branch on response status, so `redirect`, `status:200`, and `status:404` can all point at different preset bundles without changing the client selector.

{
  "triggers": {
    "redirect": ["redirected"],
    "status:200": ["default"],
    "status:404": ["not-found"]
  }
}
