- Install markdown-it@14.1.1 as server-side renderer (renderMarkdown only)
- Preserve all Joplin extensions: underline (++..++), checkboxes,
blank-line markers, softbreak→<br>, resource URIs, spellcheck attrs,
hx-* strip, fence/code/image/link render overrides
- Fix blank-line round-trip: emptyDiv/emptyP Turndown rules now return
the BL sentinel instead of '<br>' (which line 611 inflated to 4 newlines)
or '' (which made blank-line edits never save)
- Disable CSS scroll anchoring in preview editor so images flow down
naturally when text is typed above them
- Narrow the Notebook + button label and padding in the nav header
- Bump static asset version to 20260501a
Custom regex renderer's fence extraction required column-0 anchoring,
so any fence inside a list item (or with leading whitespace) was missed
and the loose backticks were mangled by the inline-code regex. Add a
list-item-nested fence pass that outdents the body and preserves the
surrounding list structure as a placeholder, plus relax the column-0
fence regex to allow up to 3 spaces of indentation per CommonMark and
trailing whitespace on the closing fence.
