The manual existed only as docs/manual/README.md, which the forge renders
and nothing else does. An installed copy of the application, on a laptop
with no network or on a tablet, had no manual it could open.
`traces manual` renders the README to docs/manual/index.html with
pulldown-cmark (already in the tree as Slint's Markdown parser, so this
adds a dependency edge and no crate). The page is one file with an inline
stylesheet that follows the system's light or dark preference, a
contents list of every section and subsection, and the pictures by their
relative media/ paths. Each heading carries the id the forge gives it, so
README.md#rating-and-flagging and index.html#rating-and-flagging are the
same link. A picture alone in its paragraph becomes a figure whose alt
text is shown as the caption, and every picture reserves its 16:11 box
before it loads, so a jump into the middle of the page lands where it
aimed rather than a screenful above. Links to design documents, which the
installed page has no copy of, point at the forge.
The page is committed rather than rendered at build time, as the gesture
book is: it is user-facing text reviewed in the diff, and the three
packagers then only copy it. `traces manual-check` fails in CI when the
committed page is not the render of the README, and the pre-commit hook
regenerates it when the README is staged.
