Applies custom transforms to HTML. If done is true, it’s the final chunk. Chunks are not guaranteed to be well-formed HTML
(they could include an element’s opening tag but not its closing tag, for example)
but they will always be split at sensible boundaries such as %sveltekit.head% or layout/page components.
@paraminput the html chunk and the info if this is the last chunktransformPageChunk: ({ html: stringhtml }) => html: stringhtml.String.replace(searchValue: string | RegExp, replaceValue: string): string (+3 overloads)
Replaces text in a string, using a regular expression or search string.
@paramsearchValue A string or regular expression to search for.
@paramreplaceValue A string containing the text to replace. When the {@linkcode searchValue} is a RegExp, all matches are replaced if the g flag is set (or only those matches at the beginning, if the y flag is also present). Otherwise, only the first match of {@linkcode searchValue} is replaced.replace('old', 'new'),
		ResolveOptions.filterSerializedResponseHeaders?(name: string, value: string): boolean
Determines which headers should be included in serialized responses when a load function loads a resource with fetch.
By default, none will be included.
@paramname header name
@paramvalue header valuefilterSerializedResponseHeaders: (name: stringname) => name: stringname.String.startsWith(searchString: string, position?: number): boolean
Returns true if the sequence of elements of searchString converted to a String is the
same as the corresponding elements of this object (converted to a String) starting at
position. Otherwise returns false.

ResolveOptions.preload?(input: {
    type: "font" | "css" | "js" | "asset";

}): boolean
Determines what should be added to the &#x3C;head> tag to preload it.

Returns true if searchString appears as a substring of the result of converting this
object to a String, at one or more positions that are
greater than or equal to position; otherwise, returns false.
@paramsearchString search string
@paramposition If position is undefined, 0 is assumed, so as to search all of the String.includes('/important/')
