How this works: "Save to this browser" updates the numbers instantly, but only on this device (stored locally). To publish new figures for all visitors, click "Generate permanent code" and paste the block into js/site.js, replacing the IMPACT_STATS block — or connect a small backend when the site goes live for true one-click publishing. The passcode is a light screen for convenience, not real security; keep this page unlinked in production or protect it at the hosting level.
