New
• Default event duration — how long a new event opens, per calendar.
• Week & day: choose an hour height, or pinch to zoom. "Fit whole day" shows all 24 hours at once.
• Tap the date in the top bar to jump to another day.

Changed
• Calendar colours reworked so event text is always readable.
• Reminders now carry Calendula's own status-bar icon.

Fixed
• Back closes the sidebar instead of the app, and its rows line up.
• Status-bar icons follow the app's light/dark choice.
