[$50 BOUNTY] [TypeScript/React] Implement Robust Error Boundaries and Component Fallbacks for Dashboard Layout

[therapyneuroflex-source]

Bounty: $50 (LT)

Area: frontend/src/components/

Current state: The frontend layout components (Dashboard, Header, Sidebar) render dynamic stat values directly. If any sub-component encounters an unhandled runtime error during render, the entire UI crashes.

What's needed: Introduce declarative React Error Boundaries around major UI layout sections to isolate component failures and provide professional fallback interfaces.

Acceptance criteria:

• Create a reusable ErrorBoundary component to catch render errors.
• Wrap the main Dashboard panel and dynamic StatCard grids inside distinct error boundaries.
• Ensure fallback UIs display a clean, non-breaking user error message matching the design tokens.

Required validation:

• Run python3 build.py
• Include the generated diagnostic .logd and .json artifacts from the diagnostic/ directory in the PR.
• Use .github/pull_request_template.md for submission.

I’d like to work on this bounty.

I’ll keep the implementation scoped to the requested frontend error-boundary work: a reusable ErrorBoundary component, wrapping the main Dashboard/layout sections and StatCard grids, clean fallback UI using existing design tokens, and validation with python3 build.py plus the generated diagnostic artifacts in the PR.
