0.3.1

Fixed

• Formulas no longer disappear from the PDF. Block and inline math ($$…$$, $…$) left no
  trace at all: MathJax renders to SVG without any text node, so the converter dropped it and
  the counter stayed at zero — meaning the summary notice kept quiet too. The PDF gave no hint
  that anything was missing. Math now shows as [Formel] and is counted. The same gap affected
  Mermaid diagrams and any other SVG-rendered element.
• Task lists keep their state. - [ ] and - [x] rendered as visually identical bullets;
  "done" was indistinguishable from "open". They now carry [ ] / [x].
• A heading is no longer stranded above an image. The orphan guard measured text lines of
  the following block — meaningless for an image, which never splits. The heading fit next to
  two notional lines, then the whole image moved to the next page and left it behind above a
  third of a blank page.

Found during the device acceptance run of 0.3.0 (2026-08-04) and fixed upstream in
obsidian-kit 0.22.0; vendored here.

Changed

• tools/sync-kit.sh stamps every vendored file with its kit version instead of only
  i18n.ts — a plain cp had been dropping the "do not hand-edit" marker from pdf/*.ts. It
  now also carries settings.ts and rewrites VENDOR.json, so re-vendoring is one command.
• pdf/layout.ts and pdf/options.ts are no longer pinned behind the rest of the vendor
  (they hung back at kit 0.14.0); the whole pdf/ tree tracks one kit version.
• check:pure is a script (scripts/check-pure.mjs) rather than a grep one-liner. The old
  pattern only matched single quotes — the project's own style — and was therefore blind to the
  double-quoted imports the vendored kit actually uses.
