 ### GTM Status
-- GTM-TW9WCD9J już wdrożony w templates/site/layout-logged.php (i layout-unlogged.php)
+- GTM-TW9WCD9J już wdrożony w templates/site/layout-logged.php

+- 2026-04-26: ZMIANA — event purchase przeniesiony na przelewy24 (post-order, pre-payment). Capturuje 100% zamowien.

-### Cookie Consent Bug
-- cookienoticepro.script.js ~linia 351: gdy analytics NIE zaakceptowane, kod wywołuje gtag('consent','update',{'analytics_storage':'granted'}) zamiast 'denied'
+### Cookie Consent (Phase 3 — COMPLETE)
+- Biblioteka: libraries/CookieNoticePro/ (skopiowana z pomysloweprezenty.pl)
+- Bug naprawiony: linia ~351 — blok else teraz wysyla analytics_storage: 'denied'
+- Dodatkowe poprawki: CSS initial hide dla acceptBtnSettingsLabel, Bootstrap 5 compat reset
+- Consent Mode v2 init PRZED snippetem GTM w layout-logged.php
