docs(pixel): remove Game Page section and validation checklist from README

bkbooth · claude · bkbooth · commit 5f15b4b54fff · 2026-04-10T16:09:53.000+10:00
Keep the README generic for all integrators. Game Page-specific details
and the validation checklist are tracked separately.

-## Game Page Integration
-
-The Game Page uses the pixel with `consent: 'anonymous'` (no PII, device signals only):
-
-```html
-<script>
-(function(){
-var w=window,i="__imtbl";
-w[i]=w[i]||[];
-w[i].push(["init",{"key":"GAME_PAGE_PUBLISHABLE_KEY","consent":"anonymous"}]);
-var s=document.createElement("script");s.async=1;
-s.src="https://cdn.immutable.com/pixel/v1/imtbl.js";
-document.head.appendChild(s);
-})();
-</script>
-```
-
-### Validation Checklist
-
-After installing on Game Page, verify:
-
-- [ ] Snippet is in `<head>` and does not block rendering (async load confirmed)
-- [ ] Page load impact under 50ms (measure with Lighthouse)
-- [ ] `PageMessage` events visible in events pipeline with `surface: 'pixel'`
-- [ ] Attribution context (UTMs, referrer) correctly captured on campaign-linked visits
-- [ ] Session cookie (`_imtbl_sid`) set and rolling on navigation
-- [ ] Anonymous ID cookie (`imtbl_anon_id`) set with 2-year expiry
-- [ ] No console errors across Chrome 80+, Firefox 78+, Safari 14+, Edge 80+
-- [ ] CSP (if any) allows `script-src cdn.immutable.com` and `connect-src api.immutable.com`
-- [ ] 100% of events pass backend schema validation (check rejected count in API logs)
-- [ ] Event volume within expected range — no duplicate events, no runaway listeners
-- [ ] Monitor for 24 hours post-deployment before clearing for external rollout
