[kanishka-2007-tech]

Description

Adds a dedicated test suite for InteractiveViewer to validate behavior under massive datasets and extreme scaling scenarios.

Changes

• Added components/InteractiveViewer.massive-scaling.test.tsx
• Added 5 tests covering:
• Rendering with thousands of interactive items
• Parallax particle rendering under heavy load
• Zoom boundary enforcement (0.5x–3x)
• Extreme keyboard panning
• Tooltip behavior within large datasets

Fixes #4363

Pillar

• 🎨 Pillar 1 — New Theme Design
• 📐 Pillar 2 — Geometric SVG Improvement

Great tests. Rendering thousands of DOM nodes in React can sometimes cause internal testing libraries to crash or timeout, so it's good to have an explicit limit verification test. Testing the bounds of the zooming mechanism and tooltip intersection limits is also excellent.

Labels Applied:

• level:advanced: Testing UI performance and large DOM rendering bounds is advanced.
• type:testing: The PR adds UI performance testing.
• quality:clean: Clean logic, properly mocked framer-motion and portals.
• gssoc:approved
• mentor:Aamod007
