- Dashboard: a browser that names no time zone (Chrome on Windows for a zone it cannot map) crashed the world clocks and the whole dashboard. One helper now reads the browser zone and every reader picks its fallback; a stored zone the browser does not know is left out instead of throwing (#2694). - Phone: a leg of a multi-leg train or flight showed only its route, and its sheet showed the first leg's seat. The day plan subtitle is one helper for desktop and phone now, so a leg names its own train or flight, platform and seat, translated instead of the hardcoded "Gl."/"Sitz"; the sheet opened from a leg shows that leg's number, seat, platform and times (#2701). The PDF export translates platform and seat too. - Journey list: the year badge named the year a journey was written, not the years of its trips; a trip over New Year shows both (#2685). - A place's description and notes are markdown in the planner but printed as raw syntax in the PDF export and on a shared trip. Both render it now through the app's sanitized markdown pipeline, raw HTML stays text (#2692). Closes #2694 Closes #2701 Closes #2685 Closes #2692
