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
