- Hilt 2.53 -> 2.59.2
- Compose BOM 2025.05.00 -> 2026.06.00
- Material 3 -> PINNED to 1.5.0-alpha21 (Expressive APIs live only here)
- AndroidX Core KTX 1.15.0 -> 1.19.0
- Lifecycle 2.8.7 -> 2.10.0
- Activity Compose 1.9.3 -> 1.13.0
- DataStore 1.1.1 -> 1.2.1
- JUnit Jupiter 5.11.4 -> 6.1.0 (with unified platform 6.1.0)
- Truth 1.4.4 -> 1.4.5
- AndroidX Test JUnit 1.2.1 -> 1.3.0
- Espresso 3.6.1 -> 3.7.0
- Gradle 8.14 -> 9.5.1 (required by AGP 9.1.1; bootstrap via two-step
  wrapper upgrade from HouseHoldKeaper's 8.14 wrapper)

Also moved kotlinOptions DSL to the new top-level kotlin {} block
(required with Kotlin 2.3+ / AGP 9.x).

 **Architecture:** Single Gradle module `:app`, Kotlin 2.1 + Jetpack Compose mit Material 3 Expressive (1.5+), Hilt für DI, DataStore-Preferences für App-Settings. Build via Gradle Kotlin DSL und Version Catalog (`libs.versions.toml`). CI über Gitea Workflows (adaptiert von HouseHoldKeaper, Flutter-Steps durch Gradle-Steps ersetzt). Alle Resourcen + Strings i18n-fähig ab Tag 1 (DE + EN).

-- [ ] **Step 6: Verify gradle wrapper works (with JDK 17)**
+AGP 9.1.1 mandates Gradle ≥ 9.3.1. Use 9.5.1 (latest stable). This step uses Gradle 8.14 just to upgrade itself — safe because no AGP is wired in yet:
 
-The system default JDK is 26, but AGP 8.7.2's compatibility envelope is JDK 17–21. Use JDK 17 explicitly for every gradle invocation in this plan:
+```bash
+JAVA_HOME=/usr/lib/jvm/java-17-openjdk ./gradlew wrapper --gradle-version 9.5.1 --distribution-type bin
+```
+
+Expected: Gradle downloads 9.5.1, writes the new `gradle-wrapper.properties` and `gradle-wrapper.jar`. Output ends with `BUILD SUCCESSFUL`.
