+# Phase 03 Plan 03: Forest Scene Summary
+
+**SVG woodland background with 4x3 CSS grid overlay rendering IndexedDB forest elements with fade-in animation**
+
+## Performance
+
+- **Duration:** 2 min
+- **Started:** 2026-03-29T11:40:00Z
+- **Completed:** 2026-03-29T11:42:00Z
+- **Tasks:** 2
+- **Files modified:** 3
+
+## Accomplishments
+- SVG forest background with sky gradient, clouds, sun, background trees, hills, and ground
+- 4x3 CSS grid overlay positioned absolutely over SVG for element placement
+- renderForestScene() loads all ForestElements from IndexedDB and renders as images with random offset
+- New element animation (fade-in + scale-up, 1.2s ease-out) via CSS class
+- Object URL memory leak prevention with tracked revocation on re-render
+
+## Task Commits
+
+Each task was committed atomically:
+
+1. **Task 1: SVG forest background and grid HTML structure** - `c9abc9e` (feat)
+2. **Task 2: Render forest elements from IndexedDB** - `e1fc5eb` (feat)
+
+## Files Created/Modified
+- `index.html` - Added forest scene container with SVG background and grid overlay in forest screen
+- `src/styles/main.css` - Added forest scene CSS: grid layout, element styling, appear animation keyframes
+- `src/forest/scene.ts` - Added renderForestScene() with IDB loading, Object URL management, animation class
+
+## Decisions Made
+- SVG element order: sky rect painted first (background), then clouds/sun, trees, hills, ground on top for correct visual layering
+- Object URLs stored in module-level array and revoked before each re-render to prevent memory leaks
+- Random offset of +-10-20px applied to each element image for natural, non-rigid placement within grid cells
+
+## Deviations from Plan
+
+None - plan executed exactly as written.
+
+## Issues Encountered
+None
+
+## User Setup Required
+None - no external service configuration required.
+
+## Next Phase Readiness
+- Forest scene ready for Plan 04 (reward flow) to call renderForestScene(db, newElementId) after generating new elements
+- Level map still renders alongside the forest scene as expected
+
+## Self-Check: PASSED
+
+- All 3 modified files exist on disk
+- Both task commits verified in git log (c9abc9e, e1fc5eb)
+- SUMMARY.md created successfully
