+# Phase 02 Plan 02: Fallback Content Summary
+
+**Static German fallback texts (greetings, forest comments, letter intros for levels 1-6) and 7 pastel SVG forest element images**
+
+## Performance
+
+- **Duration:** 2 min
+- **Started:** 2026-03-29T09:52:48Z
+- **Completed:** 2026-03-29T09:55:07Z
+- **Tasks:** 2
+- **Files created:** 8
+
+## Accomplishments
+- 10 time-of-day keyed greetings, 10 forest discovery comments, 13 letter introductions covering all keys in levels 1-6
+- All texts in simple German (max 25 words), no performance praise, nature-themed
+- 7 SVG fallback images (blume, pilz, vogel, schmetterling, reh, baum, bach) in pastel watercolor style, all under 2KB
+
+## Task Commits
+
+Each task was committed atomically:
+
+1. **Task 1: Fallback texts module** - `24bcbd1` (feat)
+2. **Task 2: Fallback SVG images** - `66f8403` (feat)
+
+## Files Created/Modified
+- `src/companion/fallbacks.ts` - Typed fallback text arrays with TimeOfDay greetings, forest comments, letter intros, and helper functions
+- `src/assets/fallback-images/blume.svg` - Flower with pink/purple gradient petals
+- `src/assets/fallback-images/pilz.svg` - Fairy tale mushroom with pastel cap
+- `src/assets/fallback-images/vogel.svg` - Small bird in blue/green tones
+- `src/assets/fallback-images/schmetterling.svg` - Butterfly with purple/pink wings
+- `src/assets/fallback-images/reh.svg` - Young deer with white spots
+- `src/assets/fallback-images/baum.svg` - Magical tree with round green crown
+- `src/assets/fallback-images/bach.svg` - Stream with stones in blue tones
+
+## Decisions Made
+- Used ue/oe/ae transliteration for umlauts in fallback texts, consistent with existing codebase convention (characters.ts uses same pattern)
+- SVGs kept minimal (under 2KB each) using gradient-based rendering rather than complex paths for watercolor feel
+
+## Deviations from Plan
+
+None - plan executed exactly as written.
+
+## Issues Encountered
+
+None
+
+## User Setup Required
+
+None - no external service configuration required.
+
+## Known Stubs
+
+None - all content is complete and functional.
+
+## Next Phase Readiness
+- Fallback texts ready for companion integration (Plan 04)
+- SVG images ready for forest reward display (Plan 05)
+- Helper functions provide clean API for random fallback selection
+
+## Self-Check: PASSED
+
+All 8 created files verified present. Both task commits (24bcbd1, 66f8403) verified in git log.
