The previous batch fix tried to move ui-tooling-preview to debugImplementation per a reviewer suggestion, but @Preview is used in MainActivity.kt which lives in the main source set, so the annotation class must be available at release-build compile time. Moving @Preview composables to a debug-only source set would let the dep stay debug-scoped - that is a Plan 02+ refactor, not foundation work.

Calendula
A modern Material 3 Expressive calendar app for Android.
Calendula is named after the flower of the same name, whose name comes from
the Latin kalendae — the first day of the month — the same root as the
word "calendar". Calendula reads from Android's built-in CalendarContract,
so any calendar source synced to your device (CalDAV via DAVx5, Google,
local, WebCal subscriptions, ...) is shown.
Features (V1)
- Month, Week, and Day views
- Read-only event details (write support comes in V2)
- Multi-calendar visibility toggle
- Material You Dynamic Color (Android 12+)
- Light/Dark theme follows system
- German + English UI
Building
Requires Android SDK 36 and JDK 17. The Gradle wrapper is checked in, so no host Gradle install is needed:
# Build debug APK
./gradlew assembleDebug
# Run unit tests
./gradlew test
# Run lint
./gradlew lint
If your default JDK is something other than 17, set JAVA_HOME explicitly:
JAVA_HOME=/path/to/jdk-17 ./gradlew assembleDebug
