v0.12.0

Added

• Notes: a page with images that have no alt text, and how many, with the
  instruction to add alt text in Google Docs. See
  ADR-029.
• Notes: a page with images cropped in Google Docs, and how many. The site
  shows such an image whole, the part cropped away included; the note says to
  check that part and to crop an image before inserting it. Publication is
  unchanged. The manifest records the count as croppedImages. See
  ADR-030.
• Notes: a page with images larger than a size the project sets, how many,
  and the largest. The size is sync.largeImageMegabytes in
  site.config.json, 2 MB unless set, read from the published files on
  every sync, so changing it needs no export. Nothing about the images
  changes.

Changed

• An image without alt text is published with an empty alt instead of
  "Image from" and the document's title, which read as a description to AI
  agents and screen readers. A page that opens with such an image takes its
  summary from its first words instead.
• A heading that holds only an image is published as a paragraph, instead of
  a heading with no words in the table of contents.
• An image with a title and no alt text takes its title as its alt text,
  and a blank title is no longer carried into the page.
• The first sync after upgrading exports every document with images
  converted through the HTML export once more, to count them, and rewrites
  the pages the changes above reach: an image without alt text or with only a
  title, a heading that holds only an image, an image inside a table, which
  loses the blank title Google gives every image, and the section pages whose
  summaries change. Other pages are left as they are; the manifest records
  the count as undescribedImages.
• A page that comes out the same keeps its page, and its manifest record now
  follows what the conversion found: the export it came through and its
  warnings, as well as the count.
