1.5.9 — 2026-07-28

• Typeface changed from Urbanist to Geist, everywhere — UI, Writer,
  Markdown view, and code blocks. Urbanist is removed completely:
  font files, license file, @font-face rules, stylesheet
  references, service-worker cache entries, and documentation.
  Geist is self-hosted as a variable font (weights 100-900, latin +
  latin-ext, SIL Open Font License) — verified in a real browser
  that the page loads it from local files with zero external
  network requests of any kind. Geist ships no italic faces, so
  italics render as a browser-synthesized oblique. Service-worker
  cache bumped (v3) so installed PWAs pick up the new font on next
  load.
