First release published on addons.mozilla.org. Functionally identical to 0.2.0 / 0.2.1, which were self-distributed; this version only adds an explicit license (MIT), a privacy policy, and build instructions for review.

Highlights
- Detects the font-family values actually in use on the page and lists them
- Override the whole page, or just one specific font-family, with Google Fonts
- Combine a Latin typeface with a Japanese one
- Search results are rendered in their own typeface; filter by language and category
- Save font combinations as presets (up to 20)

Changes apply only to the tab where you clicked the icon and are fully reverted on reload.
