WordCraft's crates/formats/src/model (07f97737) moved as it is: Flow, FBlock, Para, Inline, Fmt, tables and cells, pictures, to_doc and from_doc, picture sniffing, colours, base64 and the Dropped report. Only the paths changed (wordcraft_doc is craft_wordmodel); the report helpers are public so the format crates can call them; the image re-encoding helper stays with WordCraft's RTF writer.

craft-flow
The model every text format maps to and from: a Flow is blocks, a block a paragraph (Para:
a Kind — normal, heading, title, quote, code line, rule — list membership, alignment, spacing
and formatted Inline spans: text, pictures, links, bookmarks, fields, notes, equations, ruby,
charts, shapes) or a table (FTable of Cells holding blocks), with the document's Meta.
to_doc and from_doc convert a flow to and from a craft_wordmodel::Document. A format reader
builds a flow and calls to_doc; a writer calls from_doc (or from_doc_with and FlowOpts for
what that format keeps: fields, boxes, paragraph formatting, tracked changes) and walks the flow.
Formats that keep more than the flow holds (ODT) carry it in the optional fields (extra,
kept, …), which the plain formats leave empty.
use craft_flow::{FBlock, Flow, Fmt, Inline, Kind, Para, from_doc, to_doc};
let p = Para { kind: Kind::Heading(1), inlines: vec![Inline::Text("Title".into(), Fmt::default())], ..Default::default() };
let doc = to_doc(&Flow { blocks: vec![FBlock::Para(p)], ..Default::default() });
let back = from_doc(&doc);
assert!(matches!(&back.blocks[..], [FBlock::Para(p)] if p.kind == Kind::Heading(1) && p.text() == "Title"));
Also here: picture sniffing and sizing (sniff_image, image_px, make_img), CSS colours
(parse_color), base64 and data: URIs, list labels (ListCounter), and the one-warning-per-kind
report of what an importer leaves out to stay within a limit (Dropped, begin_import,
dropped).
Provenance
WordCraft's crates/formats/src/model (at 07f97737), moved as it is onto craft-wordmodel.
Image decoding for re-encoding (decode_bounded) stays with the RTF writer that needs it.
