More customization to blockquotes from Djot

[Omikhleia]

With Omikhleia/markdown.sile#139, Djot attributes are passed to the blockquote implementation.

See Omikhleia/markdown.sile#138 for the rationale.

What to make out of it in resilient and its styling paradigm remains to be considered.

Perhaps this could be similar, minimally, to what we did for term-definition lists = a "variant" option to pick a different (sub)-style.

[Omikhleia]

The proposal could be the following...

Djot input:

{variant=continuous}
> Lorem ipsum dolor sit amet, consectetur adipiscing elit. Sed non risus. Suspendisse lectus tortor, dignissim sit amet, adipiscing nec, ultricies sed, dolor.
>
> Lorem ipsum dolor sit amet, consectetur adipiscing elit. Sed non risus. Suspendisse lectus tortor, dignissim sit amet, adipiscing nec, ultricies sed, dolor.

Resilient style:

blockquote-continuous:
  inherit: "blockquote"
  style:
    paragraph:
      before:
        indent: false

Of course which such a mechanism, one can define any style blockquote-xxx in their resilient style file (even possibly not inheriting the blockquote style, and doing other fancy/unexpected stuff).

Another "reasonable" example:¹

blockquote-meh:
  inherit: "blockquote"
  style:
    font:
      style: "italic"
    color: darkolivegreen
    paragraph:
      before:
        indent: false

1. Well, color here raises another issue (unrelated) with Djot/Markdown input, but that's another topic for a new typesetter (i.e. how leading is currently implemented) ↩
