test(AchievementsSkeleton-responsive-breakpoints): verify Responsive …

[realtushartyagi]

Description

Resolves #7041

This PR introduces comprehensive unit tests for components/dashboard/AchievementsSkeleton.tsx to verify Responsive Multi-device Columns & Mobile Viewport Layouts (Variation 7).

Specifically, this test file (AchievementsSkeleton.responsive-breakpoints.test.tsx) verifies:

1. Standard mobile-width media coordinates (375px viewport) are correctly mocked and the achievement skeleton renders all 4 cells without errors.
2. The 2-column grid layout (grid-cols-2) is correctly declared and all 4 skeleton cells remain intact at the mobile base breakpoint.
3. No inline absolute pixel widths exist that could cause horizontal overflow or scrollbars on smaller viewports.
4. All shimmer skeleton card tiles are present and carry rounded Tailwind classes, confirming graceful visual scaling on mobile devices.
5. Mobile-specific toggle states respond cleanly when the viewport transitions from desktop (1440px) to mobile (375px) via a resize event, with the grid and all cells remaining intact.

Pillar

This PR introduces the required test coverage for Issue #7041 (AchievementsSkeleton.responsive-breakpoints.test.tsx). The tests simulate real mobile viewport conditions by mocking window.innerWidth and window.matchMedia, then assert the skeleton's 2-column grid layout, the absence of overflow-causing inline widths, graceful shimmer cell scaling, and clean rerender behavior on viewport resize events. All 4 achievement skeleton cells are verified to render correctly at every simulated viewport size. All 5 test cases pass locally with 0 lint errors and 0 type errors. Let me know if you need any adjustments!

Hey! Thanks for adding responsive breakpoint tests to AchievementsSkeleton. Guaranteeing mobile viewport rendering and multi-device column layouts don't shift during loading keeps the dashboard looking polished.

I'm assigning level:beginner, type:testing, and quality:clean.

Solid work, approving!
