;; content-on-sx — render boundary.

|
;; Rendering is a message, not a property switch: every block (and the document)
|
|
;; answers asHTML and asSx. The internal model carries no presentation — the
|
|
;; boundary format is chosen by which message you send. The document folds its
|
|
;; children's renderings, so (asHTML doc) / (asSx doc) are pure polymorphic
|
|
;; sends with no type dispatch in the SX layer.
|
|
;;
|
|
;; NOTE: no HTML escaping yet — text is emitted verbatim. Escaping is a boundary
|
|
;; concern to add before any untrusted content reaches render.
