Free Fire Sensitivity Tool Website

I need a clean, lightweight web page that displays recommended Free Fire sensitivity settings, neatly organised by phone type. When a visitor lands on the page they should first choose between Android and iPhone; from there the site instantly shows the best-fit sensitivity values (General, Red Dot, 2×, 4×, AWM, Free Look, etc.) along with a short note explaining why those numbers work well for that device group.

Core requirements
• Two clearly separated sections—Android and iPhone—with the option to expand individual phone models later without breaking the layout.
• Mobile-first, responsive design so players can read the settings directly from the device they play on.
• All sensitivity data stored in an easily editable format (JSON, CSV, simple CMS, or a small admin panel—whichever you prefer) so I can update values as the game or hardware changes.
• Fast load times; minimal external libraries. Vanilla HTML/CSS/JavaScript or a small PHP/Laravel/Node back-end is fine as long as it stays performant.
• SEO-friendly structure: header tags for each phone type, meta tags ready, clean URLs.
• A short “Tips & Guides” paragraph beneath each table so beginners understand how to apply the numbers in-game.

Acceptance criteria
1. Visiting /sensitivity automatically shows a toggle or tab for Android vs iPhone.
2. Choosing a platform reveals a table with at least five common phone models and their full sensitivity breakdown.
3. All values pull from the editable data source; changing the source reflects on reload without code edits.
4. Lighthouse mobile performance score ≥ 90.
5. Delivered as a ZIP (code + assets) and a brief README describing how to update the data file and deploy.

Once complete and deployed to my hosting, the job is done.
