/**
|
|
* Closed rich-text AST for provider content (proposal §4.5 "rich content
|
|
* contract"). Nothing outside these node types can be rendered: there is no
|
|
* node that carries raw HTML, attributes, styles or arbitrary URLs.
|
|
*
|
|
* URL-bearing fields are only ever produced by `parseSafeHttpUrl` /
|
|
* `toProxiedMediaUrl`, and the renderer re-validates them, so an AST that was
|
|
* round-tripped through storage or the network cannot smuggle a bad scheme.
