feat: add weighted global Surprise Me

[varma1221]

Summary

• Add a global Surprise me action to the home page.
• Preserve the existing company-page Surprise me behavior and keep it scoped to the current company and filters.
• Add build-time weighted-random question selection across the complete dataset.
• Remove the dice emoji from the company-page action.

Selection logic

The build pipeline now derives a company weight from the sum of available per-question frequencies, using a question-count fallback when a frequency is unavailable. Each unique question receives a question weight based on the combined weights of the distinct companies that list it. The final selection weight uses log1p(questionWeight) so every question remains eligible while highly cross-company questions receive higher odds without completely dominating the result.

The generated global payload is stored in site/public/data/global-surprise.json, avoiding runtime data-source requests.

Validation

The build-time generator prints the top 20 questions by final weight to the console for temporary ranking validation. A dedicated debug endpoint was not added. The new generated payload is covered by static-data validation.

Checks completed successfully:

• npm run type-check
• npm run lint
• npm run validate
• npm run test:validation
• npm run build

The production build generated 662 static pages successfully.

Manual testing

• Verified the home-page global action opens questions from the complete dataset.
• Verified the question details panel displays correctly.
• Verified the company-page action remains company-specific and respects filters.
• Verified the dice emoji is removed.
• Verified the new action remains usable at a narrow mobile viewport.

Closes #18

🟡 Changes recommended

The generated global payload currently stores an order-dependent per-company frequency for each question (misleading in the global context), and the new global-surprise validation path lacks corresponding test coverage.

Once you've addressed the issues Copilot identified, you can request another Copilot review.

Pull request overview

Adds a new global “Surprise me” entry point on the home page that selects a weighted-random question from the entire dataset using a build-generated index, while keeping the existing company-page “Surprise me” scoped to the current company/filters and cleaning up its UI.

Changes:

• Introduces a home-page GlobalSurpriseMe client component that fetches and selects from global-surprise.json using weighted randomness.
• Extends the build-time generator to emit global-surprise.json (and questions-index.json) and updates validation to include the new global payload.
• Extracts question topic tagging into a shared helper and removes the dice emoji from the company-page action.

This looks really good!
I checked it out in the vercel preview deployment, it works really well too!
The only changes I request are UI changes, currently the button looks a bit odd and out of place, can you maybe change it to look more clean or more standardized to our website UI?
About the mobile UI, the button doesn't adjust to the mobile UI correctly and the button becomes wide and takes up the entire width.
Please make this changes so we can move forward to merging with main.

Btw, Thanks for making my work easy by considering the @copilot review and making those changes!

Implemented in 96c9d1a. The global Surprise me action now uses a cleaner site-aligned style, and the mobile behavior no longer forces full-width so it fits naturally in the layout.

Copilot does its thing even before I looked at this. I have verified the output and everything works as intended @Vardhan-IMMIDI. You can safely merge this with a final look.
