+## Fonts
+
+The default title/stamp styling uses these fonts:
+
+- Bebas Neue for the opening title, date, and location
+- Montserrat for the bottom-left and bottom-right stamps
+
+Install them locally for the current user:
+
+```bash
+mkdir -p ~/.local/share/fonts/google
+curl -L -o ~/.local/share/fonts/google/BebasNeue-Regular.ttf \
+  'https://github.com/google/fonts/raw/main/ofl/bebasneue/BebasNeue-Regular.ttf'
+curl -L -o ~/.local/share/fonts/google/Montserrat%5Bwght%5D.ttf \
+  'https://github.com/google/fonts/raw/main/ofl/montserrat/Montserrat%5Bwght%5D.ttf'
+fc-cache -f ~/.local/share/fonts/google
+```
+
+Optional font also used during experimentation:
+
+```bash
+curl -L -o ~/.local/share/fonts/google/Cinzel%5Bwght%5D.ttf \
+  'https://github.com/google/fonts/raw/main/ofl/cinzel/Cinzel%5Bwght%5D.ttf'
+fc-cache -f ~/.local/share/fonts/google
+```
+
+Check that fonts are available:
+
+```bash
+fc-match 'Bebas Neue'
+fc-match 'Montserrat'
+fc-match 'Cinzel'
+```
